I have an SSD machine and I have no difficulties. I am not doing anything special with it. This doesn't read like your problems are related to the use of the SSD in any way. It seems to me like this is some other different problem. This type of behavior makes me think that your system is behind on memory and swapping. When the kernel is deep into memory thrash swapping "nice" won't help. Run 'vmstate' and look at the 'si' and 'so' (swap in / swap out) rate columns. A number of 0 or 1 is fairly normal. But anything larger than 1 would be an indication of swapping happening. How much memory do you have and how much of it is used by userland? Used by filesystem buffer cache? Bob
