#3951: mutt is superslow
----------------------------+----------------------
Reporter: ps | Owner: mutt-dev
Type: defect | Status: new
Priority: major | Milestone:
Component: user interface | Version: 1.8.3
Keywords: |
----------------------------+----------------------
Newer version of mutt are unbearably slow for bigger mailboxes (>20k
msgs).
1. Moving through index takes ages. Every time new page with messages is
to be drawn one has to wait seconds. This makes any faster movement
through the mailbox practically impossible.
It is probably related to some buffering mechanism, because if I scroll
back to previous page it renders instantaneously.
I use mailbox already stored in local file, so it has nothing to do with
IMAP.
It happened also quite some time ago: version 1.5.16 (2007) works just
fine, newer 1.5.21(2010) shows the symptoms. Just tried 1.8.3, symptoms
remain.
Necessary precondition is that you use customized coloring, I have approx
10 lines in the form:
color index cyan default "(~h ma...@gmail.com | ~h ma...@gmail.com | ~h
ma...@gmail.com)"
Jumping to next threads is just annoyingly slow, trying to navigate
quickly through the index became impossible.
2. Searching through mailbox is order of magnitude slower than it used to
be, not sure, whether this is the same bug.
