Reread timezone repository performance #123

Open simendsjo opened 6 months ago

simendsjo commented 6 months ago

Reading the timezone database on Windows takes a long time as Windows is very slow at opening files. By creating a combined timezone database, I'm able to speed it up from 0.800ms to 0.030ms. This helps on Linux too (went from around 0.130 to 0.016), but it was never slow enough to be a problem there.
