(1.002)
We are using MCE to monitor and manage over 20,000 devices on our network. We do a get of 20 metrics and a walk of two trees of over 20,000 devices in about 100 seconds using MCE! MCE is truly invaluable - we would not be able to scale our service without it!

The below is a test running on a Sun T5120 with eight cores each at 1.165 GHz. This chip has 32 logical cores.

## Compute time: 1.818
The Sun OS box tested here runs at 1.165 GHz.
The Sun OS box at www.tbray.org/ongoing/When/200x/2007/...
was running at 1.4 GHz.
The fastest time submitted was a perl script utilizing Sys::Mmap and 32 workers
taking 1.51 seconds.
So, in comparison and accounting for the processor speed difference, MCE is
able to perform very well utilizing 9 workers. 1.51 / 1.818 * 1.4 GHz = 1.163 GHz
