[TYPO3-Performance] MySQL connection slow?

[Dan Osipov]

I'm having a serious problem, where a connection to mySQL DB (residing 
on a separate server) takes on average 2.5 seconds. This is the longest 
task in page generation, and is unacceptable.

I don't know where to begin to determine the cause of the problem. Both 
servers are on a LAN. It could be a network issue, MySQL configuration, 
OS configuration, or anything in between... Suggestions on where I 
should look?
