Dima Computation times...

Hi there,

every once in a while I'm getting asked for "performance of distance matrix calculation". Here are some simple results I produced on my local machine (I7- details below - 16GB memory, xTour 1.24.0.3, HIGH PERFORMANCE ROUTING enabled). I calculated the distance matrices from scratch.

Overview

500 x 500 : 2.0 seconds
1.000 x 1.000 : 3.0 seconds
2.000 x 2.000 : 5.5 seconds
3.000 x 3.000 : 9.5 seconds
4.000 x 4.000 : 14.5 seconds
5.000 x 5.000 : 21.0 seconds
7.500 x 7.500 : 39.0 seconds
10.000 x 10.000 : 64.0 seconds
15.000 x 15.000 : 136 seconds
20.000 x 20.000 : 240 seconds
Feedback is welcome.

Best regards,
Bernd

For users who want to test this themselves: When testing performance of xServers and especially xDima, keep in mind that the first request after an xServer has started always take much longer then subsequent request since all data has to be read in from the hard drive and there is nothing yet cached by either the xDima or the OS.

Before benchmarking the performance of your local system, please do a few request as " warm up phase" before actually measuring.
