Hi,

I realy need some help from you. I know notting about configuration of mysql. I recently transfer my website from a share server to a dedicated server and the site its slower. The html pages open fast, but when is needed to get informations from the DB averything freezes. In the share server I could work ok with 50 user conected. In the dedicated server with 20 everything freezes. Is to slow. I don’t know what to do.

This are the specifications of my server:

CPU AuthenticAMD, AMD Athlon™ XP 2600+
psa v8.0.1_build80060713.16 os_FedoraCore 4
SO Linux 2.6.17-1.2142_FC4smp
ram: 471.21 MB
free ram: 18Mb
buffer: 3.40Mb
Cached: 221Mb

I have a DB of 200Mb

the my.cnf is like this:

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock

Default to using old password format for compatibility with

mysql 3.x

clients (those using the mysqlclient10 compatibility package).

old_passwords=1

[mysql.server]
user=mysql
basedir=/var/lib

I really need help… Thanks,

Pedro

Are you using MyISAM or InnoDB tables?

If you are using MyISAM then start by adding:
key_buffer_size=70M
To your [mysqld] section and restart.

OR if you are using InnoDB then add:
innodb_buffer_pool_size=200M
to the [mysqld] section and restart.

Because the default values for these are very small.
Then come back and say if it made any difference.

Hi Sterin,

thanks for your reply.

I had to point back the dns to the shared server because it was impossible to work in the dedicated one. So now I can’t test it with real users.

Before I redirect again the Domain I will past here the “show variables” for you to see if there are other values that I should set up and configure, and after that I Will make the redirection of dns back to the dedicated server.

Thanks
