Question & Answer :
Added June 18, 2013
Since location was nary reply and might not discovery specified benchmarks performed by others, determined to bash my ain assessments. Unluckily, my motion stays “locked” truthful I can not station this arsenic the reply, lone edit the motion. Delight ballot to re-unfastened this motion. For C#, I utilized Xamarin.Android Ver. four.7.09001 (beta). The origin codification, each the information I utilized for investigating and compiled APK packages are connected GitHub:
Java: https://github.com/gregko/TtsSetup_Java
C#: https://github.com/gregko/TtsSetup_C_sharp
If person would similar to repetition my checks connected another units oregon emulators, I’d beryllium curious to larn the outcomes arsenic fine.
Outcomes from my investigating
I ported my conviction extractor people to C# (from my @Sound Aloud Scholar app) and tally any exams connected 10 HTML information successful Nation, Country, Gallic, Polish and Czech languages. All tally was carried out 5 instances connected each 10 records-data, and the entire clip for three antithetic gadgets and 1 emulator are posted beneath. I examined “Merchandise” builds lone, with out debugging enabled.
HTC Nexus 1 Android 2.three.7 (API 10) - CyanogenMod ROM
Java: Expansive entire clip (5 runs): 12361 sclerosis, with record speechmaking entire: 13304 sclerosis
C#: Expansive entire clip (5 runs): 17504 sclerosis, with record speechmaking entire: 17956 sclerosis
Samsung Collection S2 SGH-I777 (Android four.zero.four, API 15) - CyanogenMod ROM
Java: Expansive entire clip (5 runs): 8947 sclerosis, with record speechmaking entire: 9186 sclerosis
C#: Expansive entire clip (5 runs): 9884 sclerosis, with record speechmaking entire: 10247 sclerosis
Samsung GT-N7100 (Android four.1.1 JellyBean, API sixteen) - Samsung ROM
Java: Expansive entire clip (5 runs): 9742 sclerosis, with record speechmaking entire: 10111 sclerosis
C#: Expansive entire clip (5 runs): 10459 sclerosis, with record speechmaking entire: 10696 sclerosis
Emulator - Intel (Android four.2, API 17)
Java: Expansive entire clip (5 runs): 2699 sclerosis, with record speechmaking entire: 3127 sclerosis
C#: Expansive entire clip (5 runs): 2049 sclerosis, with record speechmaking entire: 2182 sclerosis
Emulator - Intel (Android 2.three.7, API 10)
Java: Expansive entire clip (5 runs): 2992 sclerosis, with record speechmaking entire: 3591 sclerosis
C#: Expansive entire clip (5 runs): 2049 sclerosis, with record speechmaking entire: 2257 sclerosis
Emulator - Limb (Android four.zero.four, API 15)
Java: Expansive entire clip (5 runs): 41751 sclerosis, with record speechmaking entire: 43866 sclerosis
C#: Expansive entire clip (5 runs): 44136 sclerosis, with record speechmaking entire: 45109 sclerosis
Little treatment
My trial codification accommodates chiefly matter parsing, changing and Regex searches, possibly for another codification (e.g. much numeric operations) the outcomes would beryllium antithetic. Connected each units with Limb processors, Java carried out amended than Xamarin C# codification. The largest quality was nether Android 2.three, wherever C# codification tally astatine approx. 70% of Java velocity.
Connected Intel emulator (with Intel HAX application, emulator runs successful accelerated virt manner), Xamarin C# codification runs my example codification overmuch sooner than Java - astir 1.35 clip sooner. Possibly Mono digital device codification and libraries are overmuch amended optimized connected Intel than connected Limb?
Edit July eight, 2013
I conscionable put in Genymotion Android emulator, which runs successful Oracle VirtualBox, and once more this 1 makes use of autochthonal Intel processor, not emulating Limb processor. Arsenic with Intel HAX emulator, once more C# runs present overmuch quicker. Present are my outcomes:
Genymotion emulator - Intel (Android four.1.1, API sixteen)
Java: Expansive entire clip (5 runs): 2069 sclerosis, with record speechmaking entire: 2248 sclerosis
C#: Expansive entire clip (5 runs): 1543 sclerosis, with record speechmaking entire: 1642 sclerosis
I past observed that location was an replace to Xamarin.Android beta, interpretation four.7.eleven, with merchandise notes mentioning any adjustments successful Mono runtime arsenic fine. Determined to rapidly trial any Limb units, and large astonishment - C# numbers improved:
BN Nook XD+, Limb (Android four.zero)
Java: Expansive entire clip (5 runs): 8103 sclerosis, with record speechmaking entire: 8569 sclerosis
C#: Expansive entire clip (5 runs): 7951 sclerosis, with record speechmaking entire: 8161 sclerosis
Wow! C# is present amended than Java? Determined to repetition the trial connected my Collection Line 2:
Samsung Collection Line 2 - Limb (Android four.1.1)
Java: Expansive entire clip (5 runs): 9675 sclerosis, with record speechmaking entire: 10028 sclerosis
C#: Expansive entire clip (5 runs): 9911 sclerosis, with record speechmaking entire: 10104 sclerosis
Present C# appears to beryllium lone somewhat slower, however these numbers gave maine a intermission: Wherefore the clip is longer than connected Nook HD+, equal although Line 2 has a sooner processor? The reply: powerfulness redeeming manner. Connected Nook, it was disabled, connected Line 2 - enabled. Determined to trial with powerfulness redeeming manner disabled (arsenic with enabled, it besides limits the processor velocity):
Samsung Collection Line 2 - Limb (Android four.1.1), powerfulness redeeming disabled
Java: Expansive entire clip (5 runs): 7153 sclerosis, with record speechmaking entire: 7459 sclerosis
C#: Expansive entire clip (5 runs): 6906 sclerosis, with record speechmaking entire: 7070 sclerosis
Present, amazingly, C# is somewhat quicker than Java connected Limb processor arsenic fine. Large betterment!
Edit July 12, 2013
We each cognize, that thing beats autochthonal codification for velocity, and I was not glad with the show of my conviction splitter successful Java oregon C#, peculiarly that I demand to better it (and frankincense brand it equal slower). Determined to re-compose it successful C++. Present is a tiny (i.e. a smaller fit of records-data than former exams, for another causes) examination of the velocity of autochthonal vs. Java connected my Collection Line 2, with powerfulness redeeming manner disabled:
Java: Expansive entire clip (5 runs): 3292 sclerosis, with record speechmaking entire: 3454 sclerosis
Autochthonal thumb: Expansive entire clip (5 runs): 537 sclerosis, with record speechmaking entire: 657 sclerosis
Autochthonal limb: Expansive entire clip (5 runs): 458 sclerosis, with record speechmaking entire: 587 sclerosis
Seems similar for my peculiar trial, the autochthonal codification is 6 to 7 instances sooner than Java. Caveat: might not usage std::regex people connected Android, truthful had to compose my ain specialised routines looking for paragraphs breaks oregon html tags. My first exams of the aforesaid codification connected a Microcomputer utilizing regex, had been astir four to 5 instances sooner than Java.
Phew! Waking natural representation with char* oregon wchar* pointers once more, I immediately felt 20 years youthful! :)
Edit July 15, 2013
(Delight seat beneath, with edits of 7/30/2013, for overmuch amended outcomes with Dot42)
With any trouble, I managed to larboard my C# exams to Dot42 (interpretation 1.zero.1.seventy one beta), different C# level for Android. Preliminary outcomes entertainment that Dot42 codification is astir 3x (three instances) slower than Xamarin C# (v. four.7.eleven), connected an Intel Android emulator. 1 job is that Scheme.Matter.RegularExpressions people successful Dot42 does not person the Divided() relation that I utilized successful Xamarin exams, truthful I utilized Java.Util.Regex people alternatively, and Java.Util.Regex.Form.Divided(), truthful successful this peculiar spot successful the codification, location is this tiny quality. Ought to not beryllium a large job although. Dot42 compiles to Dalvik (DEX) codification, truthful it cooperates with Java connected Android natively, does not demand costly interop from C# to Java similar Xamarin.
Conscionable for examination, I besides tally the trial connected Limb units - present the Dot42 codification is “lone” 2x slower than Xamarin C#. Present are my outcomes:
HTC Nexus 1 Android 2.three.7 (Limb)
Java: Expansive entire clip (5 runs): 12187 sclerosis, with record speechmaking entire: 13200 sclerosis
Xamarin C#: Expansive entire clip (5 runs): 13935 sclerosis, with record speechmaking entire: 14465 sclerosis
Dot42 C#: Expansive entire clip (5 runs): 26000 sclerosis, with record speechmaking entire: 27168 sclerosis
Samsung Collection Line 2, Android four.1.1 (Limb)
Java: Expansive entire clip (5 runs): 6895 sclerosis, with record speechmaking entire: 7275 sclerosis
Xamarin C#: Expansive entire clip (5 runs): 6466 sclerosis, with record speechmaking entire: 6720 sclerosis
Dot42 C#: Expansive entire clip (5 runs): 11185 sclerosis, with record speechmaking entire: 11843 sclerosis
Intel emulator, Android four.2 (x86)
Java: Expansive entire clip (5 runs): 2389 sclerosis, with record speechmaking entire: 2770 sclerosis
Xamarin C#: Expansive entire clip (5 runs): 1748 sclerosis, with record speechmaking entire: 1933 sclerosis
Dot42 C#: Expansive entire clip (5 runs): 5150 sclerosis, with record speechmaking entire: 5459 sclerosis
To maine, it was besides absorbing to line that Xamarin C# is somewhat sooner than Java connected a newer Limb instrumentality and somewhat slower connected the aged Nexus 1. If anybody would similar to tally these exams arsenic fine, delight fto maine cognize and I’ll replace the sources connected GitHub. It would beryllium peculiarly absorbing to seat outcomes from a existent Android instrumentality with Intel processor.
Replace 7/26/2013
Conscionable a speedy replace, re-compiled by benchmark apps with the newest Xamarin.Android four.eight, and besides with dot42 1.zero.1.seventy two replace launched present - nary important modifications from the outcomes reported earlier.
Replace 7/30/2013 - amended outcomes for dot42
Re-examined Dot42 with Robert’s (from dot42 makers) larboard of my Java codification to C#. Successful my C# larboard achieved initially for Xamarin, I changed any autochthonal Java courses, similar ListArray, with Database people autochthonal to C#, and many others. Robert did not person my Dot42 origin codification, truthful helium ported it once more from Java and utilized first Java lessons successful specified locations, which advantages Dot42, I conjecture due to the fact that it runs successful Dalvik VM, similar Java, and not successful Mono, similar Xamarin. Present Dot42 outcomes are overmuch amended. Present is a log from my investigating:
7/30/2013 - Dot42 assessments with much Java courses successful Dot42 C#
Intel emulator, Android four.2

I inactive deliberation that Dot42 has a agelong manner to spell. Having Java-similar courses (e.g. ArrayList) and a bully show with them would brand porting codification from Java to C# somewhat simpler. Nevertheless, this is thing I would not beryllium apt to bash a batch. I would instead privation to usage present C# codification (libraries and so forth.), which volition usage autochthonal C# courses (e.g. Database), and that would execute slow with the actual dot42 codification, and precise fine with Xamarin.
