[stunnel-users] stunnel high load and lower network I/O yields

We are finding a bottleneck with stunnel for video intensive apps where it
will run with weighted CPU near 120% and network interface will yield
30.3Mb, whereas without stunnel the rates will top off near 53.1Mb during
the 10 second intervals as reported by iftop. The peaks are higher, but
this is not sustained for either case. In order to improve stunnel's
performance, is it possible to use a less intensive compute processing
encryption, or fork the stunnel per connection?
