I never had swap, but now I've set noatime on mounts and Fx cache to
0MB. It seems that the problem has gone away for now at least. Thank
you. :)

maybe after 5 years from now (at least) they finally invent direct 
controlling of flash and flash-optimized filesystem.


flash drives should be MUCH faster that hard drives, but they had to 
emulate hard drives...

 Hi,
 
 I've successfully installed FreeBSD 7-STABLE on my Eee PC 900. Just
 one problem. Quite regularly the machine becomes unresponsive. I asume
 because of something reading from or writing from the SSD, because it
 always happens when the disk activity indicator is lit and it stops
 immediately when it's turned off again. Sometimes it lasts as long as
 20-30 seconds, just when using Firefox, OOo or similar.
 
 Any ideas on how to deal with this? And just as interresting; what's the 
 cause?

just an idea (i don't have EEE so it's ideas) - EEE simulates IDE drive 
through flash just like USB drives, adding mapping layer to simulate 512 
byte sectors writes and to prevent flash wornout.


this is VERY inefficient for random writes on USB flashdrives, and 
possibly here too.


as long as NAND flash chips won't be directly accessible, and some 
flash-designed filesystem will be writted it will be like that.

just a comment - with 7.x it would be much better to make /tmp as tmpfs - 
it will then take only as much memory as needed.
