Slow Disk Drive and Slow USB Performance
June 16, 2008 12:19 am Gentoo, LinuxSo I installed Gentoo fully again on the laptop for fun. What I noticed was that the USB writes were extremely slow for my system. Initially I started blaming the USB drive or the kernel module. But everything checked out perfect from the USB perspective.
So I tried doing a disk to disk copy and found out the hard way that my disk writes on the system were horrible. The dmesg proved that I was using the old generic IDE driver that gives horrible performance.
How did I get this way? By trying to optimize the Kernel I disabled the SCSI drivers for the SATA system and was using only the IDE.
The fix for this was pretty easy but it required another recompile of the Kernel. I enabled all the SCSI drivers for the system as modules.
After the recompile of the Kernel and a reboot, perfect performance from the hard drive. I wonder how many Gentoo people have suffered the same fate.
