Thanks!

Hi All,

I've been googling for this issue but it seems like google is not my friend at the moment.  I am running Linux with 4 cpus and top command shows stunnel at 99-100% cpu.  Please help.

//stunnel configuration file

CAfile = /etc/stunnel/ca.pem

#Some performance tunings

socket = l:TCP_NODELAY=1
socket = r:TCP_NODELAY=1

# Use it for client mode
client = yes
