Mysql slow connection over lan

Hi all,

I have a problem with a drupal/mysql installation on a local area network. I have done this same setup on some remote machines, but I´m unnable to replicate it in our office lan.

The problem: when I try to connect to the lan mysql server through a local ip (192.168.1.10) the connection is desperately slow.

If I connect through localhost (on the mysql server), it goes perfect.

I have tried to debug the problems with the devel module debug info, just to see that the queries that in localhost consume 5.18ms, through the LAN went up to 40.8... and that for all of them:

localhost: Executed 249 queries in 35.39 milliseconds. Queries taking longer than 5 ms and queries executed more than once, are highlighted.

over lan: Executed 249 queries in 260.42 milliseconds. Queries taking longer than 5 ms and queries executed more than once, are highlighted.

Any idea of what can be the problem? Thanks in advance, Simon.
