Bug Description

Binary package hint: synaptic

Trying out natty, I noticed that if I do a search in Synaptic using the search button (not the quick search field), the search is extremely slow. It has been running about 30 minutes right now and the progress bar is at about 3/4 complete. It is progressing, just extremely slowly.

Hi Brian,
What apt version are you using, is it 0.8.8ubuntu3?
Do you find scrolling extremely slow in synaptic?

Yeah, apt version 0.8.8ubuntu3. Come to think of it, scrolling in synaptic is pretty slow. On my Core 2 Duo, it seems to only update the list about 2-3 times per second while scrolling, and it's hitting the CPU hard to do that.

I'll confirm this.

When I enter text in the quick search field it takes forever to scroll to the appropriate location.

With an empty search field scrolling works fine.
