Is wordpress server intensive?
 

I have a tgp/blog around 4-5k on a semi-dedicated (only 4 users) and the past 2 days, the mysql server has been crashing a few times a day. The host can't pinpoint exactly who is crashing it, but said it started after I moved to the server, even though I've been on it for almost 10 days now, 8 of them fine. Does anyone know if wordpress can handle "high" traffic on this sort of enviorment or does it need it's dedicated?

semi-dedicated, what specs?

It all depends on how you use it. It is best to keep things which don't need to be dynamic, well, not dynamic. A list of links you update once a week, for example, is something you shouldn't do through the wp link manager.

Looks like some of the plugins might actually be the problem. Wp-cron.php probably isn't a good one to have. I've just disabled some, might be running too many connections.
