Slow Loading in Roundcube

Mon Jan 27 09:03:29 CET 2014

Hello Christian,

currently I have exactly 0 emails in my inbox and about 20 mails in sub folder.
I takes about 30seconds to load the preview of a single email (from
subfolder) or to change a category.

I'm using a default installation with two domains, while trying to
troubleshoot this problem I executed initMultidomain.sh from
thimoteus' github. This had no positive or negative impact so far.

My setup consists of:

Centos 6.5 vServer on KVM hosted @ netcup.de
with LUKS, LVM and seperate LVs for mysql, imap and httpd directories.

2x Intel(R) Xeon(R) CPU E5-2620 0 @ 2.00GHz
