Fast System for ZM?

Post by madmax »

If I wanted to capture 8 640x480 color video streamsw/ motion detection at a reasonable rate with quick response from the web interface which setup would you choose?

-Athlon 64
-P4 3+GHz +HT?
-2 individual machines? 1 to capture, one to stream to clients?
-Dual processor machine? Pehaps have apache set to use processor 2 while the capture daemon uses processor 1?

any other ideas?

Thanks

Start with enough video input cards to have one video->digital chip per camera, and plenty of memory...

I tend to favor multiprocessor machines. Theoretically, with zoneminder being a collection of programs the OS should spread the processes amongst available cpus, each cpu would only need to service 4 cameras. I will check if that actually happens and post back.

I'm not sure what you mean by multi-processor aware. Generally it is the kernel that deals with the scheduling.

However as mentioned aboive, as ZM consists of several daemons all running independently there is a good chance that the kernel will tend to distribute them around the processors to make the most of the available resources.

But I've never explitictly tested it (not having a mutli-processor machine to play with :cry: )

securiteaze, or anyone else,
any evidence of Intel's HTT http://en.wikipedia.org/wiki/Hyperthreading (hyperthreading) improving performance? I know current gen p4's phased out HTT.
