Re: [henshin-dev] [Henshin] performance for loading henshin files

[Christian Krause <henshin.ck@xxxxxxxxx>]

Hi,
there seem to be a couple of tweaks for improving the performance for loading and saving EMF models, see here:

http://www.eclipse.org/modeling/emf/docs/performance/EMFPerformanceTips.html

We should try out whether any of these tricks make the loading / saving faster, and if they are safe, add them to the Henshin resource factory implementation.

Cheers,
Christian

Dear Henshin team,

as discussed today with Christian, there seems to be a performance issue
in Henshin concerning the loading of henshin-files for larger rule
systems above 100 rules.

Please find attached some example files showing the following
problematic behaviour:

case 1: 18,2 sec
loading the file Test-combined.henshin takes quite long time.

case 2: 7,2 sec.
loading instead the 4 files Test0.henshin to Test3.henshin takes much
less time, but the resulting transformation system in the memory
contains the same rules as in case 1

For bigger files, the factor between case 1 and case 2 becomes even higher.

Best regards,

Frank
