Re: Speed of current server

Dennis,
   I'm using this as an opportunity to remind the list of where we are
and where we hope to be going. I'm not picking on you.



In general, right now performance is pretty bad. 

Why?
Its a single threaded pure python daemon. End of story.

What can be done to fix it?
Well, right now we suck the whole package into ram, and then spew out to
the client. I've been meaning to take a look at that and see if chunking
out to 32k or 64k would improve things. (it would defnately improve our
memory usage)

Second thing is go into your up2date config file in /usr/sysconfig/rhn
and set the ssl option for packages to no. This helps A LOT, because now
you aren't encrypting/decrypting 1-100MB of data on each throw. (If you
have a highly hostile network, you don't want to do this)

Third is to wait for or contribute to the planned 1.3 release, which
will migrate us from this pure python daemon to apache/mod_python.
