[rt-users] RT 3.0 Speed

Hi,

I have just completed a transfer from 2 to 3 and I am seeing something
very similar:

Single Athlon 1Ghz
512Mb RAM
RT 3.0.1
Apache 1.3.27
MySQL 4.0.12
Linux 2.2.17 
perl 5.8.0
mod_perl 1.27
HTML-Mason-1.19
All perl dependencies etc met, (see below for output).

MySQL specific configuration:

datadir=/usr/local/var/mysql
innodb_data_file_path=ibdata1:10M:autoextend:max:2000M
innodb_buffer_pool_size=128M
innodb_additional_mem_pool_size=32M
innodb_log_buffer_size=8M
innodb_flush_log_at_trx_commit=1


RT3 is just running dog slow, on the same system that runs RT2 at a
decent speed. The only difference I can say other than the difference
between RT2 and RT3 is that RT3 is using InnoDB where as RT2 was not.

I've never used InnoDB before, so am ploughing through MySQL manuals and
looking at performance tweaks, however it can take 30 seconds to a minut
+ to load the first screen, and similar for any action that uses the DB.

Any suggestions, pointers or whatever, (aside from RTFM, cos I am doing
... lots) ... I would greatly appreciate it. But I can sympathise with
Dan as I am getting lots of grief and its at times taking the box right
over and slowing everything else down that runs on it.

Cheers,

Simon.
