We are about to switch to a new forum software. Until then we have removed the registration on this forum.
I am working on a sketch to download pictures from different websites. So far, that works. As some websites are kind slow I tried to speed the process up by using several threads, doing the same job on different sites.
Now the strange thing is, that if I let the program run by just one thread, it is much faster then 10 threads doing the same job parallel.
Is there any limitation of web access, threads, … for processing? Or do I understand something completely wrong?
Thanks for any help.
