78746 - History performance too slow

Status: VERIFIED DUPLICATE of bug 66907

(Core Graveyard :: History: Global, defect)

Description

[Todd Pringle]

Build ID:  2001050204

Running on a 266MHz PentiumII/ 128MB of RAM, History takes too long to open -
specifically:

When clicking on a drop down arrow next to "Yesterday" for instance, it took
about 6 seconds to open an entry with about 20 top level domain name entries.  I
believe this gets worse the more entries you have based on my unscientific
testing.  For instance, the "Older than 6 Days" entry, which has a lot of top
level domain entries underneath it, took a very long time - about 10-12 seconds
during which I couldn't do anything else within the application.

Seems to be the same situation whether the sidebar tab or history management
window is being used.

Nominating nsbeta1.

I don't think there's any way I can make this faster for beta - we need two,
fairly large things:
- implement indexing in mork, and make use of it in histoy
- switch to rdfliner

each of these are a signifigant chunk of work (5+ days)

I should add that it's unclear at this time which of these would post the bigger
gain, as I haven't profiled. My GUESS (with NO profiling involved) is that
switching to rdfliner would provide perhaps a 30% improvement, and mork indexing
would provide perhaps a 20% improvement...

I thought I had a dupe somewhere...
