After rereading the original message (Reading Is Fundamental) I tried the
tests again... *smile* Using the standard addressing (not local host) and
on the same machine I finally got the server to fail... (BTW, the static
page was around 3K with multiple graphics)
Testing box:
AMK K6-2/300 (single processor)
64 Megs RAM
RedHat 6.0
Midgard 1.2.5
The static page got to 180 concurrent requests before failing.
The active page got to 90 concurrent requests before failing.
Static page ran around 12 requests/second.
Active page ran around 9 requests/second.
