Details:
Synaptic package manager is really slow application,
I wrote path which solves several problems like:
- slow search in descriptions and maintainers
- slow sub view change
- slow first instalation "Reading database..."
I've added:
* background preload after openCache:
-preload maintainers and descriptions (sort orders on file and offset)
(time 900ms; 300ms if not first run)
-preload /var/lib/dpkg/info/*.list files needed by dpkg (time 10s with
nice -19; 300ms if not first run)
Gain:
-first search "name and description" (time from 12s to 200ms)
-first "Reading database...": few times faster
* remove unnecessary refreshView after subview list click
Gain: click on static subview list loads package list immediately (not
after 300ms-400ms)
I did not really test my code (various environments etc).
My changes are in path, I've worked on synaptic 0.63.1ubuntu7 sources.
