Multiple vicidials, one DB. laggy response

Postby rcphq » Thu Jul 24, 2008 1:43 pm

We're trying to grow the infrastructure of our call center by switching from a 2-vicidials in paralel setup to a 1 DB, 2 vicidials running on it scheme.
we've done some initial tests and found the response time somewhat laggy, has this happened to anyone? any ideas?

(where is a good place to read up on this, i figure it's somewhere in the docs, but im not in charge of that infrastructure project so i havent looked yet, any guidance would be most welcomed).

thanks!

What CPU specs and RAM specs are on your DB server?

Have you optimized your /etc/my.cnf file for these parameters?

the my.cnf hasn't been touched for special settings, where could i see where to better adapt it for this conditions?

the DB is currently setup on a old server we had lying around for testing, the servers it could end up on would be more powerfull, but we we're amazed by the noticeable lag in response

Your database needs to be the FASTEST server in the cluster.

I cannot give you any suggestions unless you tell me about the machine:

It's a dual Xeon 2.8GHz 533MHz FSB 512KB L2 Cache with 2GB RAM and two 73GB 7,200 RPM SCSI Disks using RAID 1

You should start with the huge-my.cnf file that is included by default with MySQL.

Make sure that hostname lookups are diasbled(as sp3ecified in the SCRATCH_INSTALL doc).
