Updated to the newest version.
When I did
sslrcv = 0, sslsnd=0
I get, in green:
*** Updated TCPBufferSize - TCP Receive Buffer is set to 65536 byte (note
missing line break)
*TCPBufferSize - TCP Send Buffer is set to 65536 byte*
*TCPBufferSize - SSL Receive Buffer is set to 65536 byte*
*TCPBufferSize - SSL Send Buffer is set to 65536 byte*
With those settings and TLS back on, it's transferring at around 1.25MB per
minute. That ONE test is slightly better than before, but still pretty
bad.
I tried setting all 4 to 1024000, but can't. When I copy in what you
typed, I get a javascript popup saying
*Invalid 'TCPBufferSize' - unchanged*
and in the GUI under TCPBufferSize there's a red error message:
**** Invalid: 'tcprcv = 1024000 , tcpsnd = 1024000 ,sslrcv = 1024000,
sslsnd = 1024000' (check returned '')*
I tried with the comma right after 1024000 and more traditional spacing,
same warning.
The GUI says max value is 999,999 but you've got 1,024,000 *I don't know
if you mean just 1024, added a zero or what...*
*THANK YOU*
