[XPERIA X1 General] Mark A Cilenti:
This is a new thread with the same goal as my previous performance thread ' Turbo Speed X1 ', to tweak and speed up the performance of ROM 2.

I have a silver X1i with a 16gb SanDisk Micro SD ( Class 2 ), and I have just upgraded to ROM2 through the official update facility provided by Sony Ericsson, on the UK o2 network.

First impressions of ROM 2 are very positive, subjectively speaking. However I am going to be using Benchmarks to test and demonstrate any quantitative improvements. I am going to be using Spb Benchmark, widely regarded and well respected, avaliable free from the Spb Website.

I will also include the results of SKTools5, we are all aware that results can fluctuate from run to run, but most people have this tool and it is quick to run, and can measure Memory Card Read and write speeds.

Tweak 1 - Cache Settings

These are the defualt settings that come with ROM 2, they should be the same for everyone who has upgraded, so we all start from the same level. They are captured and changed using Advanced Configeration Tools, posted below.

At first sight these settings are very similar to the defualt settings that came with ROM 1. So I changed them to settings that I found worked well with ROM1, they are as follows.

Here are the defualt cache settings and new cache settings I have tested side by side for easy reference.

SPB Benchmark Results

First the results with Spb Benchmark, defualt on the left, new settings on the right. Green indicates faster results, red indicates slower results.

Observations from Spb

1) The majority of the tests showed a speed improvement with the New Settings.

2) Test 4 shows a 20% increase in speed, and Test 6 showed a 9% increase in speed, in my opinion both results are outside natural variation.

3) The two results that were marginally slower for the new settings were less than 3% slower which I would consider to be within natural variation.

Conclusions from Spb

The results indicate a speed improvement with the new settings, a 20% increase is significant.

SKTools Benchmark Results

View attachment 175677

Observations

There is significantly more variation with SKTools, the one result which stands out is SD Read Speed which shows consistantly up to 3 X Faster, with the New Cache settings.

Conclusions

A result of 3 X faster consistantly, run after run, cannot be explained away by natural variation. This is a very good positive result.

Overall

I am pleased with the first stage of tweaking ROM 2, it seems to respond in a similar if not slightly less dramatic way that ROM 1, but still increases of 20 % and upto 300% ( 3 X Faster ) for some things is still a good days work and well worth implimenting.

I welcome all contributions on this thread from Junior and Senior members alike, on tweaking, benchmarking the performance of ROM 2. This thread is not about me, or my personality, or what I had for breakfast. This thread is about improving the performance and experience of the X1, it is for all those who...
