I went out and bought new ram and upgraded my server from 256MB to 512mb. I replaced both 128MB sticks for 2 256mb sticks and the video playback is now stuttering. I have checked dma and all settings are correct and I have even updated bootmisc.sh with the hard drive parameters suggested on the wiki.
# enable DMA
/sbin/hdparm -qd1c1u1m16 /dev/hda
/sbin/hdparm -qd1c1u1 /dev/hdc
/sbin/hdparm -qd1c1u1m16 /dev/hdb

I have checked the ram with xmem86 and everything is perfect with the ram. I am also using bobs 2X with deinterlace and also opengl snyc timing.

The part that is really baffling me is what top is now showing:

top - 14:20:59 up 1:16, 2 users, load average: 4.64, 4.23, 3.98
Tasks: 101 total, 1 running, 100 sleeping, 0 stopped, 0 zombie
Cpu(s): 2.8% us, 3.8% sy, 26.2% ni, 1.0% id, 66.2% wa, 0.0% hi, 0.0% si
Mem: 383852k total, 378648k used, 5204k free, 1352k buffers
Swap: 1180768k total, 0k used, 1180768k free, 173680k cached

Are there parameters I need to update within the kernel to tell it I have gone from 256mb to 512mb? I assume this is done automatcally.

I notice when checking processes that I have duplicates on some things and I dont know if its becuase I have dual processors:

383MB. That is a bit strange. Are you sure you don't have one 256 and one 128 in there? (e.g. the shop or factory may have messed up so check the part numbers on the RAM chips)

Here is what my top shows with a 512MB and a 256MB DIMM:
Code:
top - 12:24:45 up 8 days, 23:37,  3 users,  load average: 1.43, 1.46, 1.27
Tasks:  84 total,   2 running,  82 sleeping,   0 stopped,   0 zombie
Cpu(s):  0.3% us,  4.0% sy, 95.4% ni,  0.0% id,  0.0% wa,  0.0% hi,  0.3% si
Mem:    773184k total,   653364k used,   119820k free,     6632k buffers
Swap:   396136k total,        0k used,   396136k free,   308584k cached


Other things to check:
Code:
cat /proc/meminfo
ls -l /proc/kcore

Well the chip says 256 but its running as a 128MB. Ive disabled commercial flagging and now I'll be running it for a few days to see if anything improves.

LOL i just checked my machine again during a record without commflag and here is top now.

top - 23:35:59 up 7:05, 2 users, load average: 0.10, 0.16, 0.16
Tasks: 102 total, 1 running, 101 sleeping, 0 stopped, 0 zombie
Cpu(s): 1.3% us, 4.8% sy, 0.0% ni, 92.2% id, 1.7% wa, 0.0% hi, 0.0% si
Mem: 383852k total, 378808k used, 5044k free, 4872k buffers
Swap: 1180768k total, 0k used, 1180768k free, 261372k cached

Wow the guys werent kidding that commflagging is crap. I havent seen load averages this low in a while. I guess issue resolvfed so far.
