I tried reproducing the slowness problem you mentioned since one of my
boxes is Redhat 9 but was unable.
I tried the following:
1.) scripting lengthy "ls -la" in a telnet session to remote machine.
2.) scripting rsync <username>@<hostname>:<remotefile> <localfile> for
JPG file about 160K in size.
When installing modules, I got the same "default pty only handles 155
bytes" message, also another message saying that raw pty was ok, and
handled 512+ bytes. This was when running "make test" on the Expect
module. Setting both $exp->raw_pty(1) and $exp->raw_pty(0) on different
trial runs before spawning either process didn't seem to make a difference.
Both processes took just a second or so each.
I'm trying to think of what could be causing your problem. If you're using
Expect to spawn rsync, it's the rsync process that's moving the data; not
expect. expect is just it's parent and thus getting STDOUT from the rsync
process, so I'm thinking the amount of data rsync is moving between the
websites in itself should be irrelevant. Are you running the most current
versions of everything? If you can post some of the relevant code I'll
take a look when I get a minute

I am quite sure it is a expect problem because if I run the rsync process
independent of expect (i.e. manually entering the password at the prompt
insteading of having expect module to automate the procedure), everything
runs just fine. One more piece of evidence is that I didn't get this
warning message about default pty can only handle 155 bytes when I
installed it on redhat 7.2, and the module works perfect on that system. I
wonder if rehhat 9.0 is doing something funny that messes up the expect
module.
