Fri Jan 30 14:21:10 CET 2009

Hello,stunnel-users

     I have two BCM5820 SSL accelerator card in one Freebsd 7.1 host. But
when I plug in two ssl accel card  and  make stress test by Web Application
Stress Tool , I get same banchmark ,about 70reqs/s , 50% cpu usage, as one
ssl accel card in box. On another word, it seems only one accle card is
working another one is idle.  Is there someone has simialer problem as me?
 How to make the another card  work?
