Huh.
32-bit binary on 64-bit OS vs native 64 bit binary on the Linux VM's.
I love how the default compiler likes generating 32-bit binaries for some silly reason.
BTW, at 20 VUPS, SSH2 is almost usable.
Yup.

Yeah, that might. ;)

In any case, I don't mind the overhead of the small Linux VM underneath them and they will soon all be on a large-ish server in a colo rack as I sell my apartment. Sampsa might leave London, but SAMPSACOM stays behind :)
The large-ish server should definitely help. ;)

Really? I've gotten 20 VUPS on both.

Which version of SIMH and do you remember to SET CPU IDLE?

And yes set cpu idle was specified on both, in fact the ini files are identical except for network adapter name changes.

There s something else going on here. I m not sure who originally analyzed the file to decide that the format was Stream-CR (although given that the analysis was done on RSX, we can probably guess :-)

The thing is, the file isn t Stream-CR it s Stream-LF
$ dir info.txt;1
Directory SYS$SPECIFIC:[FAL$SERVER]

So the stuff about Stream-CR is bogus and a red herring, and I don t know why Sampsa had trouble.
