12:17 domain finally removed !

WOW 10 minutes to remove one domain !

This command is also slow:

pure-pw userdel turystyka.tylkofakty.info -m

That's probably this:

When executed from shell it takes about 5 seconds so why it's taking so long from Kloxo php ?

[MRatWork]

What's code for just 5 seconds?.

We have to wait for reboot. Even hdparm -t /dev/sda takes ages to complete on all disks.

I'm on kernel: 2.6.32-504.3.3.el6.x86_64 while latest is 2.6.32-504.30.3.el6.x86_64

Weird - it was removing one domain about 7 minutes, then removed 5 domains in about 30 seconds.

Finally no load and no downtime
