I’ve managed to optimize the performance of my Hac4/GPS data merging script.

Optimized Version

2,33s user 0,06s system 89% cpu 2,677 total

Old merge and libxml-ruby

13,06s user 0,15s system 91% cpu 14,382 total

Old merge and rexml

26,86s user 0,21s system 96% cpu 27,987 total

And this is the track which I used for the tests. The track has 1554 trackpoints. I took this route on Saturday.
