[XML-SIG] Performance question

[Bryan Pendleton]

I was trying to figure out what sort of XML Parser
performance I could expect out of pyxml. I'm using
Python 2.2.2 under Windows 2000 with pyxml 0.8.1.

I wrote the following trivial little program, and it
seems to be showing me that I can get between 20 and
25 parses per second on my PC. Is this a reasonable
result to achieve? I was hoping to be able to get 
many hundreds of parses a second, so getting only 20
or so was rather alarming.

Is there anything I can do to make this code faster?

thanks,

bryan
