Is the eee pc 900 with a low write speed on SSD disk. From time to time, apparently, there is a reset of caches to disk, and it's time to crash all applications that are trying to work with the disk. Large enough, sometimes up to 30-40 seconds. OS is Archlinux. What can you tweak the kernel somehow remove these brakes?
If it matters, the file system ext2 runs on top of lvm.
