User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4 Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4 I think I have found an area in Firefox that needs improvement. I am running 1.04 on Win XP SP2 (Pentium 4 2.4 GHz, 248 MB of RAM) and am trying to load the Microsoft Security Catalog, mssecure.xml, with a file:// style URL. You can download this file here: http://go.microsoft.com/fwlink/?LinkId=18922 This file is 2,124,091 bytes large, 33,028 lines. When I load the page: IE 6: 16 seconds, 23,080 KB of memory used FF 1.04: 43 seconds, 133,524 KB of memory used When first started, IE 6 uses 16,444 KB of RAM and FF 1.04 uses 20,488 KB of RAM. The way I measured memory usage is through the Windows Task Manager. Based on these results, I believe there is a problem with FF 1.04 on Win XP. -John Taylor Reproducible: Always Steps to Reproduce: 1. Download and uncompress http://go.microsoft.com/fwlink/?LinkId=18922 2. Open firefox and this the mssecure.xml file using a file:// url 3. Watch memory usage before and after this page is loaded. Actual Results: Memory usage sky-rocketed and very slow load time. Expected Results: FF should have used much less memory and loaded faster. Part of the slow load time was paritally due to the fact that my system has only 248 MB and FF 1.04 was using 133 MB of this memory.
