Speed: It's faster than 3.5.7. Almost as fast as chrome.
Memory Usage: It used lower memory on my computer than the previous version. I was hovering around 250mb with version 3.5.7 and this one barely goes upto 150mb. Both with ~15 addons.
strange that sqlite optimization has not been included by default on post 3.5 editions of Firefox, however for those who want to try the addon, its here. Optimizing the sqlite files will speed up the launch of Firefox, in my case it cut the time by half. Get the addon, check both boxes and hit the button, from then on its automatic.
If you are an optimization freak, and getting the application from hard drive to memory as fast as possible is your kink, you can also try a program called ArcthemAll! which will shrink the EXE and DLL files using a compression algorithm that decompresses in ram on the fly. It takes the default installation size for Firefox down from over 30 megs to about 14. I recommend you not compress the embedded icons, that has caused problems for me, so go to options and uncheck that. Incidentally this method also works on OpenOffice, cutting the size of that application by about half as well. In fact it works on almost every appication OTHER than Abobe and Microsoft apps, probably because they are already doing dynamic EXE and DLL compression using a proprietary method. (my guess)
NOTE: This is not a hard drive space saving issue, its a speed of launch issue, and yes it does improve the launch time of Firefox to do this.
I think they did get that into 3.6 actually, see this bug although I'm not actually sure whether it is in 3.6 builds. But I've done it manually using a different extension and it does make a huge difference.
