Major Whenever Jenkins is "fully loaded" and somebody attempts a connect via browser it takes about 10 seconds until Jenkins' main page appears. Every subsequent attempt is answered immediately. This state remains for a couple of minutes. So there's an amount of time that needs to pass until a "first" connection attempt takes 10 sec again, and so on...
Any idea what could cause this? (Bug vs. misconfiguration). No interesting log output appears.
