Status: RESOLVED DUPLICATE of bug 91044

(Core Graveyard :: History: Global, defect)

Description

[Azat]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.3b) Gecko/20030210
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.3b) Gecko/20030210

Always slow when opening a particular day's URL list - takes 5-8 secs,
the same with scrolling one by one (1-2 secs), or by page (6-7 secs).

It's ok when the history list is not grouped by day.

Reproducible: Always

Steps to Reproduce:
1. Open Mozilla 1.3b (or 1.2.1) with big (>2Mb) history.dat file
2. Open History in window (Go/History) or in Sidebar tab.
3. Try opening a day's list or scrolling by page
Actual Results:  
Beach ball spinning for 5-10 secs

Expected Results:  
Should be more responsive - at least as on other platforms (even MacOS 9)

Confirmed using FizzillaMach/2003022103. My 867 KB history.dat file just took
26.5 seconds to display as History grouped by day. Grouped by None, it displayed
in 3.5 seconds.

A serious performance problem. Raising Severity to major.

CONFIRMED ON ALL WINDOWS BUILDS OVER THE LAST SEVERAL MONTHS. As soon as history
gets some real size to it, like after 2 months or so, it is very slow opening. 
My file takes 20 seconds to open.  History issues don't seem to get any attention.
Please change this to All for OS.
