[XPERIA X1 ROM Development] China_1:
11-27

New update:

1. Add 826x (one of the fastest manila rom!), twinge's rom (very light!)

2. Update EnergyROM and Christian's ROM to the latest version.

3. I recommand 826x! it's really fast and stable. Such a pitty that i haven't tested it before, although a lot of friends has recommended it in my thread.

4. It's good to see that the performance of Energyrom increased, especially during the GPS loading test. Maybe due to the new kernel?

5. Suprisingly to see that christian removed manila from his panels!

6. I tried to test some other ROMs, but failed. Including: Russell Eclair XPure (I couldn't donwload) and X2 Rom Port (my X1 just hang-up after flashing).

NO more updates. I hope I can continue this tough job, as long as it's still useful for some X1 users. :-) Well, since a lot of chefs are quitting X1, I don't know how long will my job be still useful?

New update:

1. Added Laurenti's ROM. This is the LITEST ROM I've ever tried! It's only 55MB! As we all know, EnergyROMs are always larger than 200MB, and even SGXU's ROMs or X2 ROMs are over 100MB. So, Laurenti cut a lot of functions, even including CHOME and Connection Setup (which means you have to setup your connection by yourself). It has the best performance!

2. Added Xara V1.2. This ROM is the extension of Jerpelea's X2 ROM. Well, it's performance is obviously better.

3. Updated EnergyROM and Valkyrie 7.3. It's great to see Agent's coming back!

4. Used GPS software (called Kailide or KLD, which I use very often in mainland China) to test the performance of the ROM. It's much easier than using SPB benchmark. One more thing is, I always use File Explorer (WM build-in) to test the open speed of Windows Folder. If I use Resco File Explorer, it'll be much faster.

5. Divided all the ROMs into two categories: with Manila, and without Manila. So, I compared the parameters within each category. It's much easier for you to compare and choose.

6. NO more updates. I've tried to download and test 826x ROM, but failed.

7-17

As I've promised, I'm updating my thread within July.

1. Updated all the ROMs to the latest version.

2. Added Jack's ROM according to many suggestions. I found that this is the FASTEST ROM with manila, even faster than X2-010b without Manila! And it also has build-in support for Chinese Simplified, Chinese Triditional and Japanese. So, it is a good ROM!

3. Added Genesis's ROM. Thanks a lot to GCCF65, who gave me the data (I didn't test this ROM by myself).

4. Due to some reasons that I haven't found, the SPB Benchmark compare function is not working, in my laptop as well as my desktop (maybe due to some changes of the service from SPB?). So, I have changed the performence test method from 'SPB benchmark' to 'open windows folder speed'. I know it's not very accurate, so if someone know a better (and easier, please understand that I'm only an individual person) method, please tell me. Otherwise, this seems to be the only choice.

5. I'm very sorry that I couldn't test ever ROM people request. I'm just doing my best. So, for those ROM I missed, I'll try them in the future (but WM6.5 only)

1.Updated all the ROMs to the latest version. X2-R3AA35-005 is still under development, so the result is not so good.

2.Added Christian's ROM. I found that it's very interesting! Both tilewave and manila are available, as panels! I'm now using it for my X1, and hopefully it's stable. And, the kernel version is rather old, so Christian should update it soon.

3.Added 'memo' to each ROM, describing some other useful information.

You my find the attachments for all the results.

Updated X2 ROM to latest 006 version.

It seems that this ROM is really fast! The bootup time is much shooter than the others (without Manila of course), and SPB Benchmark is also good. The only problem is that, it's not stable (as always).

Added Touch-IT ROM as so many ppl required.

But the result seems not so good (as well as my personal experience). What's more, 2 test functions of SPB Benchmark even failed. I don't know the reason.

There are some other small modifications. Please see the attachments for detail.

I have updated the ROM comparasion table, as following:

1. New ROMs. EnergyROM: 4/1; Valkyrie: V6.3; UnOff: Xperialeo & Xperialeo Win7; X2: 016 (Not updated). I'm sorry that I couldn't find the latest Touch-IT ROM for test.

2. Add bootup time. According to the results, EnergyROM is the fastest (actually not much difference).

3. Benchmark improved. This should be the most interesting field of the table. After analysing SPB Benchmark (it is still one of the best benchmark software on the market, even quite old), I found out that:

3.1. The indexes are the higher the better.

3.2. The 'SPB Index' is useless. It's just a weighted sum of all indexes. So, we should pay more attention on the subindexes.

3.3. The benchmark results are not stable. When I did the same test for the same ROM in the same enviorment, I found out that the results are different! So, I did 2-3 times of test for each ROM, and used the most reliable results.

3.4. The benchmark results are not much related to the applications installed. I have done the same test for same ROM, on a clean ROM and a loaded (software, SMS, contacts, call logs, etc) ROM, and I found that the loaded ROM is only 2% lower than clean ROM!

3.5. Here are some descriptions of sub indexes:

3.5.1 CPU: almost the same for every ROM (that's for sure).

3.5.2 file system: It seems that Valkyrie V6.3 is so fast! And the rest ROMs are almost the same. The advantages of Valkyrie are on write and copy of multiple small files. So, I think maybe this is due to the file cache or buffer setting. I think chefs should know this.

3.5.3 Graphics: Again Valkyrie V6.3 trumph! And the rest ROMs are almost the same. I think it may be related to the driver or something. I think chefs should know this.

3.6. After benchmarking, I have run another test by my own eye. I used file explorer to open the '\Windows' directory, and see the time cost. I found out that Valkyrie V6.3 didn't have too much advantages. So, I think the benchmark results are only for reference. But anyway, I still think they are still some kind of useful.

3.7. My test method:

3.7.1. SPB Benchmark V1.6.

3.7.2. Copy SPB Benchmark to Main Memory

3.7.3. Remove SD Card, Turn off phone

3.7.4. Restart

3.7.5. Skip Word Test & IE Test

3.7.6. Unplugged

You may find the attachments as all the benchmark results and comparasion table restuls (0406).

Finally, I'd like to say thanks to all the chefs. And, I'd like to say something for myself. I'm only an ordinary guy, who's doing this for the convienence and reference for someone who might be in need. I'm not related to any chef, I'm not a phone lab, and I have completely NO personal benefit or donation for doing this. So, if my work could help you, that's good; if not, or even 'mislead' you, please forgive me, since I have no intention for that.

Cheers,

First of all, I'd like to thank so many cooks that contributed so much for our X1. Without you guys, my X1 was just any ordinary phone.

I found that quite some people here were asking for the information about ROMs, which one is better? Stable? Fast? Less power consumption? etc. Since I have used some ROM series (chaning frequently, as you could imagine), I'd like to share some personal opinons here.

After a whole day working, I made a Comparison table, as you can find in attachments. Please remind that, in EnergyROM and Valkyrie columns, the first number means NO Manlia, and second number means WITH Manlia.

About Benchmark Result (also in attchments):

I couldn't find out a proper benchmarking software. The only 'famous' one is SPB Benchmark V1.6, which was made almost 2 years ago. I'm not sure whether it is still accurate or not, since M$ has already upgraded their OS from WM 5.0 to WM 6.5. The funny thing is that, I don't know whether the numbers mean the higher the better, or vice versa (there is no . According to my user experience, I think the result is: X2 > UnOff X1.5 > Valkyrie /EnergyROM (No manila) > Valkeyrie/EnergyROM (with manila). If someone is the expert of this, or knows some great WM Benchmarking software, please let me know.

Finally, I'm not a cook or expert on this. Definitely I might make some mistakes, and that means NO offense to any cooks or personnals. I just want to contribute some efforts to someone might in need. I also want to use this for the decision of my X1 ROM.

Cheers!
