Description

The following scenario

- Core upgraded to 0.9

- Client upgraded to 0.9

- OSX Mountain Lion

- Having channel and private message buffers from freenode.net network

- When starting the client

- when choosing any buffer for the first time

- There is unresponsiveness of 5-10 seconds before channel is opened, the application goes to unresponsiveness mode

Below is the stacktrace from the slowdown grabbed from Xcode Instruments.

Note: There is noticeable backlog of events, but the issue did not appear on 0.8 and it also happens for buffers having only recent history (< 3 days, only couple of messages)

History

#1 Updated by miohtama almost 11 years ago

Also if it was unclear this happens only for my freenode.net buffers, not for other networks (ircnet, quakenet, irc.mozilla.org)

#2 Updated by miohtama almost 11 years ago

Looks like clearing the ignore list resolved the issue.

#3 Updated by sandsmark almost 11 years ago

I suspect that it is partly because the QRegExp is recreated for every line.

#4 Updated by jeroendeneef almost 11 years ago

I also have the issue on Windows 7.
However, my ignore list is empty.

#5 Updated by Bombe about 10 years ago

I have moved the regex creation into the IgnoreListItem and that seems to have sped up the process of initally filling new buffers. However, there is still a noticable delay.
