[jboss-user] [Performance Tuning] - Re: JVM pauses periodically

Hmm. I'm curious, what is the machine doing during those 4-30 seconds? Is it burning CPU or I/O maybe? Is the JVM in RAM completely or are portions of it paged out to disk? You could run "vmstat 2" in a terminal next to "tail -f acces.log". As soon as you see the access log stall, check the vmstat to see what the box is doing, cpu or disk.
