  • Perhaps the page Troubleshooting:Performance should be merged with this one, with the Troubleshooting / Performance category handled as a redirect? They're pretty much the same information, but this page (Optimizing Performance) has MUCH more content... - DStulken 01:43, 5 January 2009 (UTC)

NFS over TCP? Does anyone have a reference for NFS performance being better when using TCP? The only case I know of this being potentially the case is with high latency links. For LAN connections, as far as I know, UDP is faster.

Sata disk performance

For SATA disks it could be usefull to tune your disk a bit for large reads. If your disk is mounted as sda (as you can see if you enter 'mount' in a terminal you can change it as:

echo "512" > /sys/block/sda/queue/max_sectors_kb
echo "256" > /sys/block/sda/queue/read_ahead_kb

IVTV 10.2 driver

Enabling VBI on version 10.2 of the ivtv driver is not a good idea. IRQ overloading is the result.

nodiratime and noatime

'nodiratime' is a subset of 'noatime', so there is no need to specify both: specifying 'noatime' will use both.
