How to tune system settings for smooth media/PVR (system also does video surveillance, speech)
Hi, I'd kindly aks for some guidance. I have Asus Pundit P4 2.4G under Suse 9.0 and get occasionals stutters on live tv and watching recordings or DVD (but system should be powerfull enough). Since my PC is integrated home server, also does video surveillance, serving music files, speech synthesis etc... Where could I find any guide how to tune this system to do smooth PVR being one of top priorities ? How to structure priorities in such system ? There are quite some applications that do take a lot of CPU instantly, but then settle down most of the time (video surveillance for instance) - so average use is small, but sudden bursts probably cause small stutters in video playback. How to tackle this problem. Beside priorities there must be some other possibilities too ? Regards, Robert.

Hi Robert, I don't have 9.0 (I'm still on 8.2 since it works fine for me...for the most part), but in 8.2, you can go into the YaST control center->hardware->IDE DMA , and turn on whatever it shows in there. I had a stuttering problem watching DVD movies too, until I did this, and now all is good. Maybe this is all you need to do, so I hope it helps. John
The software raid HOWTO that comes with 9.0 (/usr/share/doc/howto/en/html/Software-RAID-HOWTO.html) shows results for RAID (1+0) - so I'm thinking that this is possible. However after trying for a day or two I cannot figure out how to make this combination work using the yast partitioner tool. Is this supported? Do I have to use a different tool? I have an Epox 4PCA3+ motherboard with a builtin Highpoint hpt374 controller (six IDE channels in all). I have 9.0 installed on an 80GB drive off of the main IDE controller and have four 120MB drives, each on its own IDE channel that is attached to the Highpoint chip. The controller supports RAID 1+0, but I wanted to compare the performance of the htp374 versus just using software raid. I've been reading that in a lot of cases the software raid performs much better than the cheap BIOS-based hardware raid. This is for a file server and I was hoping to have one large partition instead of two. Thank you - Richard
Richard, When I installed my Suse 9.0 I had a hard time to get it not to use the soft raid, but the hardware controller. The problem was that I partioned the raid drives as type Linux RAID 0xFD and the installer then did the rest automatically, meaning installed the soft raid. Guenter Richard Mixon (qwest) wrote:

Guenter, As long as I put the "hde=noprobe hdf=noprobe ... hdl=noprobe" at the end of the "kernel" line in the /boot/grub/menu.lst, I have no problem getting the Yast partition utiltiy to honor the hardware raid. Otherwise both the IDE and RAID drivers compete for the same drives. My problem is the opposite - how to define a "1+0" raid using software raid.
