[Server-devel] Memory use with SSL connections

[Douglas Bagnall]

hi

I'm testing a slightly modified ejabberd 2.0.1 for OLPC, and am seeing
quite high memory use -- a 1GB machine is unreliable beyond 2000
connections.  There are pictures here:

OLPC's XO laptops use (old style) SSL connections, and these results
are in the same order of magnitude that Sean Dilda reported in May:

Does anyone have any tips, patches, or configuration options that
might help?
