After rebuilding tcl and naviserver (current) from source, with -ltcmalloc, my
naviserver is stable.
One small thing: I can crash naviserver on ctrl-c exit fairly easily:
[02/Jan/2014:11:41:01][15491.7fee7ed75700][-conn:magnatune3:8] Fatal:
nsthreads: pthread_join failed in Ns_ThreadJoin: Invalid argument
I conducted two stress tests that went well.
------
A trivial stress test with 200 threads in naviserver, calling a page that just
does:
<%= [clock seconds] %>
ab -n 2000 -c 200 http://magnatune.com:9000/timer2.adp
yields
Requests per second: 150.44 [#/sec] (mean)
Performance did not substantially change as I upped concurrency, nor does it
look at that different with tcmalloc linked in. However, this tcl test might
be too simple to see tcmalloc performance effects.
-----
A "long page load" test, of:
ab -n 2000 -c 200 http://magnatune.com:9000/timer.adp
against:
<%= [after 5000] %>
<%= [clock seconds] %>
was made to see what would happen if requests came in faster than they could be
fulfilled. A minthread of 5 was set, with a maxthread of 200.
Good news: naviserver did indeed spawn new threads to deal with the backlog.
