Hello,

you should use another methods to manage the PIDs of your forked processes, for example the shm_* functions (shared memory) or sockets (a simple and ipc).

Take also a look on libevent, you can do asynchronous programming :

Hello,

how would I use memcached as cache of this thing?

I am running now some 130 child and db and filesystem seems to be limiting factor – I still got over 60% of memory unused and very low cpu usage.

Thanks

Thanks John, It's definitely a rough script right now, but I'm glad it's working for you. I was in the same place as you with a huge script execution time. This brought some huge report building scripts down to a reasonable execution time. This was more or less the realization that scripts can run concurrently in the background, and then just figuring out how to keep track of them.

Thanks for the awesome script! I own a domain tools site and have implemented your script on our Type-In Traffic Finder tool. Execution has gone down from 40s to 1m to consistently under 10 seconds. I've been looking for something like this forever since our host doesn't let us use fork(). Thanks again!
