Re: BFS for the power kernel
 

Overall performance is great, but I confirm freezes (not more than 20 sec) on high mem load and hard I/O (rebuilding tracker db, browsing in microb, angrybirds, fapt-get update; browser and addressbook suffer, others perform rather well and I can use phone just fine)

I use your vm config and schedtool commands

Thanks a lot, this is awesome

Re: BFS for the power kernel
 

Well I'm a bit confused now. Just to check I enabled laptop_mode again, started FAM and did an update while I played some music through MediaBox and surfed on TMO with microb. I had no audio stuttering and no performance issues at all. It's still wonderful.

What the hell was going on before all day long?

Re: BFS for the power kernel
 

Are you sure you have ONLY settings from the above mentioned post? Because I can assure you, with those settings (and original scheduler, i.e. kp46) my device feels and behaves exactly (if not better) as the one from n900 ad . But it is with default values in /proc/sys/vm/ (excluding swappiness)

@Tigerite what I saw while playing with io congestion problem is that lower page_cluster value is, better UI responsiveness is. And nr_requests requests have to be that high in order to have both fast io and responsive UI. Did you try uncompressing easydebian image (or other very big file) to check the difference between low (32) and relatively high (512) values.

Re: BFS for the power kernel
 

Did you make a benchmark with dd before and after? It's not my goal to copy your device or setting 100%, I'm just asking if you did a benchmark and if you can share it? I did one, and I can confirm that I modified your post to make the benchmark be faster with my device but I'm using other tweakings too.

Here a benchmark without my tune-up tools:

/dev/mmcblk0p1
900000+0 Datensätze ein
900000+0 Datensätze aus
460800000 Bytes (461 MB) kopiert, 25,3318 s, 18,2 MB/s

/dev/mmcblk1p1
900000+0 Datensätze ein
900000+0 Datensätze aus
460800000 Bytes (461 MB) kopiert, 28,351 s, 16,3 MB/s

Here with my tune-up tools:

/dev/mmcblk0p1
900000+0 Datensätze ein
900000+0 Datensätze aus
460800000 Bytes (461 MB) kopiert, 21,748 s, 21,2 MB/s

/dev/mmcblk1p1
900000+0 Datensätze ein
900000+0 Datensätze aus
460800000 Bytes (461 MB) kopiert, 27,0826 s, 17,0 MB/s

/dev/mmcblk1p1 is a 8 GB Class 6 SD-Card.

I use this script dd if=/dev/mmcblk0p1 of=/dev/zero bs=512 count=9000000

Re: BFS for the power kernel
 

No, did not do it in that way, my goal was different. And having class2 sansisk my sdcard io speed will be far lower than yours anyway :D.

TBH I did not make any benchmarking, how am I supposed to benchmark something like "UI responsiveness"? I am not saying that with my settings you will achieve maximum possible io speed, but overall system speedup and responsiveness gain. Nor I am saying my settings are the best ;) .

Just out of curiosity I will ask you the same question I have asked :

How is your system behaving while uncompressing qole's easydebian archive or downloading torrent at high speed?

Re: BFS for the power kernel
 

Thank you for your fast reply, but I don't have interest in uncompressing easy-debian atm, and I think I don't use your tool to download torrent files anyway. Maybe I can tell you if you post a benchmark before and after with your setting and with your device.
It's not an excuse to me that you have only a Class 2 SD-Card. If you want you can calculate a relative in percent. Is that mathematical correct saying?

Re: BFS for the power kernel
 

and which dd are you using?

Re: BFS for the power kernel
 

d & d. Deaf & Dumb. I didn't know I have a choice? It's not the Busybox version nor the Busybox extended version.

Re: BFS for the power kernel
 

WTF? Are you high man? I am out.

Re: BFS for the power kernel
 

No, and I want not do it again, but it's really stange your question as a developer you should verify your settings but I think it's this one here: /opt/maemo/usr/bin/gnu/dd.
