Hi I have just bought a lenovo thinkpad E550, and installed Ubuntu 14.04 onto it but I am running into major performance issues. Like 8 + seconds to launch any application from startup, Firefox runs incredibly slow it won't run a video smoothly. The hardware is certified to work with Ubuntu (my exact spec)
http://www.ubuntu.com/certification/hardware/201411-16167/
I have tried changing between integrated Intel graphics and the amd card.
Changing CPU setting in BIOS.
Installed preload and prelink
I have done all updates to drivers and tried changing graphics drivers.
The laptop has a broad well i7, 8gb of ram I don't think it should be as slow as it is any help would be much appreciated.
Thanks Lewis

. For the last one, do it while the computer is under some load.preload
can cause significant load on a computer.prelink
, I don't know.
