[Labs-l] Performance at tool-labs compared with TS

Sun May 5 14:26:47 UTC 2013

I'm not sure for what it should be useful to spend hours to move 
everything to bots, if the toolserver is a running reference. The tool 
is running since 2007 so it's not anymore beta.
Btw: I don't understand the documentation of "bots", somebody should 
clean it up, so that I know where to start.

My idea is more to simplify the sql query to make a new benchmark, but 
today the toolserver is not stable enough for this, I get a lot of 502.

The answer for your question about db, filesystem, cpu, memory, remote 
api is here:
https://wikitech.wikimedia.org/wiki/Nova_Resource:Tools
and
https://wikitech.wikimedia.org/wiki/Nova_Resource:Tools/Help
or not?
I simply following the documentation.
