> So, how many megabytes are in fact pre-loaded by IE that are not used by Mozilla? Did I understand correctly that it was only 1.93MB? That's surprisingly little..

Agree, but afaik this is code only, not data. And, unfortunately we 'll probably never learn if other system libraries contain undocumented IE support. But as I said before, perhaps a clever IE startup procedure would give the impression of lightning fast startup time without having anything but the UI loaded. While I don't appreciate MS tactics of bloating its operating system, sometimes their programming techniques are brilliant.

To further explain why Mozilla startup time is so long, I looked at its dll usage. Mozilla uses 129 dlls (!) and this (together with heavy registry reads, according to a known bug) is the primary reason for its dependency on the hard disk subsystem performance. Indeed, Mozilla startup time is greatly affected by hdd speed, pio/udma/scsi mode, disk fragmentation etc. There may be a big bloat here and, unfortunately, only marginal improvements have been done over the last 3 months (most of them unnoticed, except a recent 10% reduction in reload time).
