Description Christoph Thielecke 2014-06-29 09:13:34 UTC

When moving a lot of messages (~8000) from mixed maildir ressource to maildir ressource mail responds very slow. This means it freezes for a while, then gui was refreshed and again. This effect seems to be same on opening a maildir ressource folder containing a lot of messages or marking all messages in this folder.


Reproducible: Always

Steps to Reproduce:
1. go to a folder containing a lot of msg (> 5000)
2. select all
3. right click -> move msg to other maildir ressource folder
Actual Results:  
- files are moved but gui hangs during move process for longer time 

Expected Results:  
- gui should be stay in usable state on messages move is in processs

I moved from mixed maildir ressource to maildir ressource.

Thank you for your report, Christoph. As KDEPIM SC 4 and Akonadi 1 is unmaintained, I am closing it. For the case of a pure maildir I reported this issue as:

Bug 364114 - moving a folder within one maildir resource is extremely slow and inefficient

I bet the behavior with mixedmaildir resource would be similar to what I observed. But feel free to create a bug report about moving within mixedmaildir and mention it as related in above bug report or add your findings to my bug report in case they are similar enough.
