The litmus test was always a copy/paste into an ssh client on a windows box. Didn't matter if I was connected on the LAN or over a relatively slow DSL link. The new daemon seems to be throttling quite a bit. The paste takes a while to paint on the screen, whereas before it was lightning-quick, at least until it locked up. Should I be concerned? A zmodem file transfer on a link that tests with bing to get ~50 Mbps only got about 800 kbps. Seems a little slow.. I'm not complaining, though. No more crashes is good. > mouring@etoh.eviladmin.org wrote: > > > > Can you verify this against the latest snapshot at: > > http://bass.directhit.com/openssh_snap/ > > > > 2.2.0 is very old release.
