Hello Massimo (all) this days I'm reading about horizontal scale architectures, key/value and graphs db's, etc. and the awakening in cloud computing enviroment In the last reading, I saw "Redit" benchmark of about 50 to 100 thousands req/sec with standard linux box.
I know those values are due to DB architecture of key/value (and they are really incredible), but: -what thing is really limiting 1000 req/sec in web2py? cherrypy/apache? mysql/postgres? wscgi/fastcgi? web2pyframework? python? -what do you think would the upper limit (req/sec) be in the better production enviroment case (great linux server/s, apache/cherokee?, best connection) -As a matter of curiosity, have you ever though in implementing the API for any of such databases? Redit? Tokyo? couchDB? regards, alex f P.S as always i'm sorry for my poor english El 21/07/2009 15:52, mdipierro escribió: > - Are there any large web2py installations that I can quote as an > example > > Not that I know and handle>1000 requests/second. > > - How are the issues of caching (say rendered pages) handled?
