performance issue when import reactor module before os.fork()

Question

Hi,all

i got a performance issue when trying to do:

from twisted.internet import reactor
#some codes here
pid = os.fork()
if not pid:
    #some codes blahblahblah
    reactor.run()

this caused very low performance and i didn't find useful informations from the official documentation, i believe it because i import reactor module before os.fork(), any idea?

Answer 1

Can't you use subprocess instead of os.fork?
