Fine, i should definitely give it a try. If my app is not thread safe but respond in a decent time, can i benefit from a multithread server (for a socket problem) if i use a lock for every page like that : I use webob... lock = Lock() def my_application(environ, start_response): req = webob.Request(environ) res = webob.Response() res.content_type = 'text/html' try: lock.acquire() # my app... res.write('ok') finally: lock.release() return res(environ, start_response) > > On Fri, Jan 30, 2009 at 1:52 PM, William Dode <w...@flibuste.net> wrote: > >> Hi, >> >> I've a problem with a web app wich freeze periodicaly.
