[tahoe-dev] initial results from scaling up

[zooko]

Folks:

Brian Warner wrote a load-test generator and took some measurements  
of a tahoe grid under constant load.  You can see his notes in the  
"System Load" section of The Performance Page:

http://allmydata.org/trac/tahoe/wiki/Performance#SystemLoad

"So far, Tahoe is scaling as designed: the client nodes are the ones  
doing most of the work, since these are the easiest to scale. In a  
deployment where central machines are doing encoding work, CPU on  
these machines will be the first bottleneck. Profiling can be used to  
determine how the upload process might be optimized: we don't yet  
know if encryption, hashing, or encoding is a primary CPU consumer."
