Rt getting slower

RT Users
1

Hi,

We have rt installed into a AMD Athlon 700 with 128 Ram and a Linux 2.4
OS with apache, qmail and mysql running.

There are 3 people working all the day with the ticketing system, and it
is very slow. To display a ticket it is about 30-60 seconds.

What is the average time a ticket gets to display?

Is there any way to speed up rt? we have about 3000 tickets into the
database, some of them are spam and are as status dead. How can we
delete this tickets?

It seems like a kernel memory leak, from my experience…

I’m running RT on an AMD 450 with 128MB, and it runs fine. I had set up a
test machine (I think Pentium 200, 64MB) and it would start out ok, but then
crunch to a halt within a half hour. This machine was running kernel 2.4.8.
The 2.4 kernel before .11 or .12 had a leaky VM; this would cause anything
to slow down.

The 450 machine is running kernel 2.2.19 and is fine. Which version of the
2.4 kernel are you using? I would consider upgrading (or downgrading to
2.2) if it is less than 2.4.12.

I’m using kernel 2.4.2. It’s a default RedHat 7.1

I was monitoring the server, and everytime someone opens a ticket, there
are a lot of disk accesses… The memory is ok, and the swap is not
used…

Whichi database are you using? If you’re using mysql, updating to the latest
DBIx::SearchBuilder in CPAN will drastically improve performance.
(perl -MCPAN -e’install DBIx::SearchBuilder’) After that, you need
to shut apache all the way down and start it up again.On Wed, Nov 14, 2001 at 05:04:15PM +0100, Carles Amigó wrote:

It worked!

It is about 10 times faster.

Now, my rt is running fine

Thanks a lot :slight_smile:
