Hi,
our scenario (was):
server1: 5.0.32-Debian_7etch1-log
server2: 5.0.32-Debian_7etch1-log
Hardware-wise (attention, Vmware, see below) they're equal: ~1GHz CPU at at
minimum 2GB ram.
Suddenly about 4 to 6 weeks ago, server1 started getting serious problems with
spontaneous corrupted
not sure about it's CPU performance, but the
information I've is that when connections start hanging and the effect
basically multiplies, the CPU load goes aup.
Does this sound like a possible bottleneck?
thanks,

we've enabled /var/log/mysql.log on our server (5.0.24a on Debian

Hi,
what is the best way to match german umlauts like 'ä' also their
alternative writing 'ae'?
For example I'm searching for übersee and I also want to find the word
uebersee in the database. The words are actually names of persons.

is there, performance wise, any difference whether I create one index
for multiple fields or each field with its own index? I'm running 4.0.16.
