[Pyssh-discuss] Performance Issues

[James M. <pro...@sh...>]

Hi,

Got a performance issues here...

~/tmp/pyssh
$ time ./uptime 
uptime
 01:01:06 up 3 days, 15:01,  5 users,  load average: 0.08, 0.10, 0.09

 $ 

 real    0m7.736s
 user    0m0.040s
 sys     0m0.020s

 See the attached "uptime" script. Based on your own test code.

 Here's the same thing with the openssh "ssh" command:

 ~/tmp/pyssh
 $ time ssh earth "uptime"
  01:02:16 up 3 days, 15:02,  4 users,  load average: 0.26, 0.13, 0.10

  real    0m1.393s
  user    0m0.016s
  sys     0m0.004s

Also notice that PySSH seems to open up a pty by default.
Should it do this ? (ihmo, I think it shouldn't).

Perhaps have in the constructor of Ssh

def __init__(self, username, host, port, pty=False):

cheers
James
