Every time I start Tomcat and do a ps -awx there appears to be around 35 different instances of Tomcat in memory at the same time. Is this normal? Does it interfere with performance?

This is normal, and represents Linux's concept of threads. A thread in Linux is implemented as a process. Even though it says each is using X amount of memory, in reality, they're all sharing the same heap, so it's not taking up extra memory.
