I have something weird going on with my workstation, like see it says 42.1%wa, whenever I get to this it becomes so slow, any ideas what can be done, how I can identify what's causing it and all?

update: i just did import of MySQL backup (mysqldump) to both systems... load went to 3-4 on both of them, in fact slower system was running lower load average then faster system but not by much.. anyway here is output...
[root@wcmisdlin02]# time gzip -cd mysqldump-uftwfdb1.uftmasterad.org-phplist-20110223.sql.gz | mysql -p phplist2
Enter password:

[root@wcmisdlin03 tmp]# time gzip -cd mysqldump-uftwfdb1.uftmasterad.org-phplist-20110223.sql.gz | mysql -p phplist2

so on one it took 159m and another one it took 463m oh yeah... and here is htop from one of the machines (faster one) when it's "idle" http://pastebin.com/qG1MQCA0 and when it's doing import http://pastebin.com/qRZpQKt3
