Well when I did that I noticed that VSZ spikes to 175000 or about that as soon as it gets a request. Is this normal? RSS would stay at about 6000
Probably. What you need to watch is the RSS. I don't see this explosive growth of VSZ (stays at 45MB), but our configurations is probably different.
VSZ is influenced by very many things, and includes future virtual address space reservations not yet allocated. The threads library allocates a fair bit of virtual address space (not memory) to support the threads. This happens on the first cache disk I/O operation.
