Very Important Note To Increase The Wm5 Spped

[ahmedkom]

I have noticed in all the roms coocked by Bepe Rom Kitchen there is some kind of Problem that decrease the speed of wm5 , it is the rgu and dsm files in the rom under windows folder these are the registry fles that we can exclude them from the rom after they will be saved in the rom these ara about 100 files with 1 or 2 kb size but this decrease the speed of windows folder , the way to exclude them safely coock the rom as usual first start createOS.exe it will generate the TEMP Folder then start the createROM.bat it will build the boot hive and the stopes and ask you to press any button to continue this is the time to delete the rgu and dsm files go to search and find all the rgu and dsm files and be sure to search the hidden files too because most of these files is hidden and when you finish o back to create ROM.bat and finish the rom Building and the first thing you will notice is the speed of opening the windows folder .

Note: you can exclude all the unnessery files that we dont need like the help files *.tm and the note files *.pwi and the word files *.dot etc...

That's quite interesting. I'd noted the slow performance in opening "/windows" in Total Commander and I'd often wondered if this impacted the phone. There are way too many files in there, but it was an issue on WM2003 as well and has it's root in desktop Windows. Every time the filesystem has to retrieve a file from there, it has to lookup it's information in a table. While there are ways of writing fast lookups, reducing the input set is often far better. As "/Windows" is quite possibly the busiest directory on the phone, any boost here has to be worthwhile.

Thanks ahmedkom for bringing up this interesting subject, for although there is a tremendous speed gained by mamaich's virtual page pool the Hima beats BA 3:1 when it comes to openning the /Windows dir.

This is true even if the Hima ROM compared to was prepared using Bepe's ROM cook tools. But, then again as you mentioned the BA .dsm & .rgu files are a lot more in numbers compard to the the Hima ROM.

Would you mind sharing how much speed improvement in number of wait cursor 360 degree turns was gained by eliminating those reg & .dsm files? My almost fully loaded BA displays /Windows dir & files after 4 wait cursor turns as against 1.5 turns of a similaryly loaded Hima (using Resco Explorer as File Mgr.).

Cheers!

sure, imagine how fast it's going to be if you delete all files from /windows !!

Honestly, when a 400Mhz CPU is not enough to display a listing of 100 files, something is veeeery wrong. The only reason i put up with with this, is that there's no alternatives with the big screen and gsm phone.

Anyhow, I have latest Helmi build and in calendar just going from day to day, back and forth within the same week is slow noticeably slow. It's obviously re-reading big chunks of data from flash every time, no matter how many times you go between Thur and Fri.

So, given that calendar app is so obtuse, it would be nice to have a file / disk cache on OS level -- which i believe Helmi ROM already has but somehow it aint working...

yeah i just realised Helmi's RAMdisk is just a partition for temp files in ram...
