Install 2.5.2(16158)
set 'TCPBufferSize' to : sslrcv = 0, sslsnd = 0
tell me if TLS speed is better or not
set 'TCPBufferSize' to : tcprcv = 1024000 , tcpsnd = 1024000 ,sslrcv =
1024000, sslsnd = 1024000
are there any performance improvements?

Betreff: Re: [Assp-test] Very slow TLS sessions - Windows server
Could this be the problem? Is OpenSSL even used by ASSP for receiving
email? I feel like it's not, but thought I'd put this out there.
OpenSSL 1.0.1h 1.0.1h / 0.9.8
OpenSSL-lib 1.0.2g 1 Mar 2016 1.0.2g / 1.0.1h
I have OpenSSL binaries installed in c:\openssl, and that is 1.0.2g from
https://slproweb.com/products/Win32OpenSSL.html
I don't know what 1.0.1h OpenSSL ASSP is seeing. Can you tell me what
would
need to be updated to make that be 1.0.2g AND DO WE CARE?
Could that version mismatch be causing the terrible slowness when
receiving
large attachments?
I looked through all other modules, they're all at or later than the
recommended minimum version (updated through Activestate's PPM)
For now I've got TLS off, but that's not viable long term.
Oh and there appears to be plenty of processing power on this machine (12
cores, 2+ ghz, 32gb ram)
THANK YOU
