The first is to check what is taking so long. Ie you can take a look at network
traffic going on between client and server or at least take a look at server
processlist during these 15 seconds.

Can you connect from the same (server) host fine ?

Typical issue is DNS problems. MySQL resolves host name of the client which is connecting. Check how quick is "nslookup <clientip>" on server.

MySQL caches resolved ips which would explain why previous server version was running fine.

I was also could suggest to downgrade back to 4.0 and see if problem goes away to ensure it is server version problem.
