Fast System for ZM?

madmax · Post by **madmax** » Thu Oct 21, 2004 3:58 pm

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.

im still waiting for your post back...

just kidding.

btw, anyone can confirm me if ZM is multiprocessor aware?

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

)

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.
