It seems to be quite fast on my PIII-850 laptop computer. It is as fast as IE6 and faster than Netscape 6.2.
However, it does not handle Java Applets (at least the one that I have tested). I have IE6 & Netscape 6.2 installed and both handle the Java Applet in question with no problems.
This does look like it will be a kick-ass browser when it is finished.
