Background:
Sun Fire 4800
Solaris 8 2/02
OpenSSH 3.5p1
OpenSSL 0.9.7
I have a user with a Java program that prints out 15000 lines of output (a few
columns of numbers). When we connect to our Sun Fire using SSH protocol
version 1 the output displays smoothly, but when we use version 2 the display
is "choppy" and pauses intermittenly. If the output is shunted to a file the
program execution time is the same regardless of the protocol version.
I also wrote a quick Perl script that produced similar output and the same
symptoms were experienced. Both programs are attached.
Is protocol version 2 inherently slower then version 1 or is there something I
don't know about? We haven't made any radical changes to the sshd
configuration.
Thanks!
