Speedup recycling distance matrices...

Postby Bernd Welter » Wed Mar 09, 2016 4:20 pm

Hi there,

for those who recycle distance matrices (deleteBefore=false, deleteAfter=false):

In case of increasing response times during function calls please assure to use the latest version of xTour.
We fixed a bug in 1.20.1.3 which caused the following behaviour / effect (not obvious at the first glance):

  • Existing distance matrices which grow over time grab more and more ressources - check whether this is necessary at all. Some of you might flush the DIMAs from time to time (this statement is always valid :lol: even with 1.20.1.3+).
  • WIth versions before 1.20.1.3 the server computed too many of the cells in a suboptimal way - though the quality of the output was ok the performance of the computation decreased slowly in the background.
Best regards Bernd
