[Imaplib2-devel] IMAP4_stream select() is SLOW after open()

[Dave A. <da...@bo...>]

Check it out.  The first run is with imaplib2, the second with imaplib.

--8<---------------cut here---------------start------------->8---
pluto:~ dave% time python -c 'from imaplib2 import *; s = IMAP4_stream("/opt/local/libexec/dovecot/imap"); s.open(); s.select("INBOX")'
imap(dave): Info: Connection closed in=20 out=721
imap(dave): Info: Connection closed in=18 out=694
python -c   0.04s user 0.02s system 0% cpu 30.159 total
pluto:~ dave% time python -c 'from imaplib import *; s = IMAP4_stream("/opt/local/libexec/dovecot/imap"); s.open(); s.select("INBOX")' 
imap(dave): Info: Connection closed in=20 out=721
imap(dave): Info: Connection closed in=18 out=694
python -c   0.04s user 0.02s system 64% cpu 0.086 total
--8<---------------cut here---------------end--------------->8---

If I don't try to open(), it goes fast:

--8<---------------cut here---------------start------------->8---
pluto:~ dave% time python -c 'from imaplib2 import *; print IMAP4_stream("/opt/local/libexec/dovecot/imap").select("INBOX")'           
('OK', ['44'])
imap(dave): Info: Connection closed in=38 out=1070
python -c   0.04s user 0.02s system 34% cpu 0.161 total
--8<---------------cut here---------------end--------------->8---
