I've been using Firefox for a good while now, and I like it. A mate who knows his stuff says he much prefers IE7. I thought I would do a little comparison. I've always known that Firefox is a bit hungry for memory, and I thought that I would see which program used the most.
Firefox, sitting there doing nothing but display my home page (iGoogle with a load of bookmarks, and a few links to BBC, weather, Wikipedia, etc.) is gobbling 21MB of RAM. If I open IE7 and go to the same page, it's using slghtly less - 20.6MB.
So far, so comparable. However, they start to show some difference when you start opening tabs in the same window. The memory usage for 1, 2, 3, 4 and
5 tabs open simultaneously (all on the same URL) is as follows:IE7 - 20.6, 30.7, 39.2, 46.7, 54.0 FF - 21.0, 23.9, 26.0, 27.6, 29.9
So IE7 uses fractionally less memory with one tab open, but uses an additional 8.4MB on average for each new tab you open. FF, on the other hand, asks for an average of 2.2MB per new tab. Not scientific, I know, but perhaps indicative of the two programs handling things very differently.
Anyone the faintest idea why?
