I've been a long time opera user, but now I'm trying to find an open source equivlent. Unfortunately, I'm not having alot of luck.
I've tried Konqueror 3.1.0, Mozilla 1.3, Galeon 1.3.3, Dillo 0.7.1, Links 2.1pre8, Firebird 0.6 (milestone release).
Konqueror vsz: 30856 rss: 18928 (not including kdeinit)
Galeon vsz: 46940 rss: 26088 (not including gconfd and bonobo-activation)
Mozilla vsz: 43552 rss: 24968
Firebird vsz: 33852 rss: 19576
Opera vsz: 20992 rss: 14600
Links vsz: 8432 rss: 2856
Dillo vsz: 6572 rss: 3348
(browser caches, cookies, location bar (except Galeon's), etc were cleared. Home page was google. Resources reported by ps -aux)
I was most surprised at Galeon and Firebird. The resources they were using were much higher than I would have expected for "slimmed" down versions of Mozilla.
Links and dillo clearly win in terms of resources and load time as well as initial rendering speed (first visit to a page). On subsequent visits, opera appears to win. Perhaps it utilizes cache better than any other browser (or at least it seems that way) as repeat visits are instantaneous.
However, links and dillo are still lacking in some major areas at this time :-(
Galeon and Mozilla do seem to render the best for me, though. Opera (QT static rpm version) and Firebird (binary version) don't seem to have been compiled with anti-aliasing font support -- guess I need to try compiling them myself?
Any other browsers I should try?
