HTTPS is a tremendous CPU hog and will eat up plenty of RAM. In general, a 2ghz CPU will max out with 20 concurrent HTTPS requests. More than that, you're not really stressing the server.
if you really need to test HTTPS, I would recommend keeping each client machine to 10 threads. Most of the sites that require heavy HTTPS use hardware accelerators. I personally don't recommend using software HTTPS if the expected HTTPS load is more than 10-15 concurrent. for example, a 450mhz P3 can reliably handle 3-5 concurrent requests. More than that the server will crash. this is primarily a hardware and IO limitation. peter lin On 5/10/05, Elli Swift <[EMAIL PROTECTED]> wrote: > Hi all, > > I am load testing an HTTPS application and I'm continually running into this > out of memory error: > > [GCException java.lang.OutOfMemoryError: requested 8208 bytes > > The garbage collection comes along but just doesn't seem to be clearing out > enough room.
