I have a Linode VPS running a single Wordpress blog. It has been running just fine until today. The admin panel is snappy, but the site is very slow. I am still finishing the site, so there shouldn't be any traffic.
When I go to mydomain.com it takes 45+ seconds to load, then each click on the link takes about the same amount of time. I didn't update any WP plugins (or WP), but I did add a google analytics plugin a week ago, but seemed fine. I disabled that and no difference either.
I tried rebooting nginx, and then rebooted the whole machine... still slow. My "free -m" output is:
user@myserver~ $ free -m total used free shared buffers cached Mem: 469 147 321 0 3 45 -/+ buffers/cache: 98 370 Swap: 511 0 511
The weird part is nothing has changed in the last few days....Any ideas?
