'pure-pw' 'usermod' 'domain.com' VERY SLOW !!!

[Spacedust]

Mustafa - the pure-pw user mod is very slow on my server. Why is this hapenning ?

Code: [Select]

18:10 Jun/25/2013: 0:  [(__system__:/usr/local/lxlabs/kloxo/httpdocs) 'pure-pw'  'useradd' 'mojanowadomena5.pl' '-u' 'admin2' '-d' '/home/admin2/mojanowadomena5.pl' '-m']
18:10 Jun/25/2013: pure-pw usermod mojanowadomena5.pl -N '' -m

This is causing a delay about 20-25 seconds when adding new domain !

It seems it's not pure-pw.

SOMETHING TAKING ABOUT 20-25 SECONDS HERE BUT PURE-PW NOT RUNNING IN PS AUX -- WHAT IS THIS

It's not related to kernel version or hardware. It's only something inside Kloxo :/

[MRatWork]

Pure-pw is part of pure-ftpd. Maybe you need investigate pure-ftpd config

[Spacedust]

Tested and pure-pw takes less then a second.

Got it:

Looks like one CPU is busy receiving some enormous JSON:

Mustafa please fix it !

[Spacedust]

Finally got it !!!

It was mmail table inside database. It's full of old customers accounts which is causing very high slowdowns in my Kloxo-MR. Probably it's some data from Kloxo official that Kloxo-MR is unable to read properly.

As soon I replace this file with blank from another Kloxo install my Kloxo is flying ! Domains are adding within just 10-11 seconds not 40-50 seconds

How can I properly rebuild it ?
