Hey all,

I've lurked here for a little while but haven't popped in to say 
anything til now ;)

I've been doing some performance analysis of a qpsmtpd instance I have 
set up.  Using async with SPF,database-driven rcpt to 
checker,anglebrackets,logging/file,queue/smtp-forward can drop ~76msgs 
per second to invalid senders and deliver ~23 msgs per second to valid 
recipients.  I'm guessing that the slowdown of the latter would be due 
to the non-async nature of the smtp-forward plugin?  Has anyone 
rewritten it in an async way and/or anyone have a better way for me to 
eventually queue this to a postfix installation?  In addition, do these 
figures line up with anyone else's?  This is v4 of qpsmtpd-async running 
on a dual 2.8ghz xeon with 4gb of ram with -j 4 (and it beats on the cpu 
pretty good during the stress tests).

Thanks all,

Tom Callahan
