I have a Magento web server (CentOS) that uses a crossover cable to connect to a MySQL database server.
The other day, I upgraded the Magento server. I disconnected the crossover cable from the old Magento server and plugged it into the new one. I was able to connect to MySQL, but it took about 90 seconds. When I tried to open the webpage it timed out basically.
Why would this be so slow? What type of caches, etc do I need to clear? I restarted both servers completely just to make sure it wasn't some random service.
