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?
top - 15:44:02 up 93 days, 4:29, 16 users, load average: 1.94, 1.86, 1.24 Tasks: 206 total, 1 running, 203 sleeping, 2 stopped, 0 zombie Cpu(s): 3.8%us, 4.2%sy, 0.0%ni, 49.6%id, 42.1%wa, 0.2%hi, 0.2%si, 0.0%st Mem: 3969460k total, 3585412k used, 384048k free, 65896k buffers Swap: 2031608k total, 9200k used, 2022408k free, 1701636k cached
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: real 159m34.126s user 2m14.677s sys 0m10.757s [root@wcmisdlin02]# [root@wcmisdlin03 tmp]# time gzip -cd mysqldump-uftwfdb1.uftmasterad.org-phplist-20110223.sql.gz | mysql -p phplist2 Enter password: real 463m15.483s user 3m53.825s sys 0m23.454s [root@wcmisdlin03]#
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
