Reduce the font, both (Netscape and IE) have this option. I used it at home 
(800x600) and don't needed it at work (1024x768).

That's very close! the benchmark says your computer is XXX MHz compared with 
normal Pentium, no MMX Pentium. There are 10% of difference due to a much 
better cache strategy used in MMX CPUs so you should spect 220 MHz from the 
Benchmark ;-) 

In some days I'll upload a new table using geometric average, that's a little 
bit better for comparisson in this case (can be much better in other cases).
