[web2py] Re: Processing taking a long time in web2py?
Okay thanks. I've been looking at profiling my application and I'm running an apache webserver. Do you know how I would run this? I don't have a local machine. 1. python web2py.py -F profiler.log -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.

Thanks for the reply. I understand that they are different things. I was wondering if you could point me in the right direction to somehow be able to speed this up? Or at least find out where the time is being spent. Web2py adding ~20 seconds is quite a lot of time. In the future I will be using a library, but for now I have to use this external process.

hiding behind auth doesn't get you protected by DDoS. opening a process inside a web2py app vs pure python depends on you comparing oranges to apples. web2py env with the default webserver is a threaded env, your pure python process probably isn't.

[web2py] Re: Processing taking a long time in web2py?
I'm asking why opening a process in a python script takes much less time than opening the same python code/process in a web2py application. Also yes I will consider your second point but I think I will hide it behind authentication On Thursday, 17 November 2016 22:53:50 UTC, Niphlod wrote: > > well... you're asking why opening a process in python rather than doing it > directly takes more time. no wonders there: of course it takes more time! > Especially if your process writes lots to stdout/stderr that python needs > to collect. > > BTW: never ever ever run ANY external process from the webserver: you > could easily be DDoSed AND you incur in lots of issues (random timeouts, > memory issues, leaks, and aforementioned slowness). > -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.

[web2py] Re: Processing taking a long time in web2py?
well... you're asking why opening a process in python rather than doing it
directly takes more time. no wonders there: of course it takes more time!
Especially if your process writes lots to stdout/stderr that python needs
to collect.
BTW: never ever ever run ANY external process from the webserver: you could
easily be DDoSed AND you incur in lots of issues (random timeouts, memory
issues, leaks, and aforementioned slowness).

It would be easier to understand and solve your problem if you share the code. -- Resources: - http://web2py.com - http://web2py.com/book (Documentation) - http://github.com/web2py/web2py (Source code) - https://code.google.com/p/web2py/issues/list (Report Issues) --- You received this message because you are subscribed to the Google Groups "web2py-users" group.
