Bruce: in the future, you should scp large attachments to your
/home/montrose/public_html/ directory on moria, and you can fetch them
via http://freehaven.net/~montrose/. The majordomo system catches mail
that's too big and refuses to forward it to the list. (I count this as
a feature. :)

Subject: Results of stress testing the current version of the Onion Router

The attached pdf files are reports that were generated by the WebLoad 
software for the test that I performed.

The reports that begin with pvm_fix_or were for the test being run through 
the onion routers. The reports with
pvm_fix (without the _or) were for the test being run directly to the 
servers without going through the onion routers.

When the test began data seemed to be flowing well through the onion 
routers, but as the load increased things deteriorated quickly. After the 
test completed, I attempted to bring up my browser which I setup to proxy 
through the onion router and it failed. The onion_routers are still 
running, but they appear to be hung.

I will attempt to duplicate this problem with LogLevel = debug to see if I 
can get any clues as to why the onion routers are hanging. FYI, I ran this 
test with LogLevel = err and I saw no output in the log files for the onion 
routers. I don't know if this is because there were no errors detected by 
the onion routers or if the output buffers were never flushed to the log files.

Any suggestions are welcome.
