Performance tweaks for 12.10

view story

http://askubuntu.com – I am running 12.10 on a Two year old Sony Vaio laptop (i7 with 8gb ram and ssd disk) Overall performance nothing like as snappy as I would have expected. I am using the Nvidia proprietary driver. Might that impact performance? Also fans on the laptop seem to be thrahing hard all the time. Otherwise any quick tweaks that can be applied to make the machine fizz along a bit faster would be appreciated. Thanks Matthew (HowTos)
