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.
