NetBeans GC performance on Windows 2000 version 5.0 running on x86
The graphs below show the effect of various java lineswitch settings on garbage collection in NetBeans
Each value is the average from a series of runs, and the standard deviation is shown by the bracket
bracing the value end of each bar.
The current tests are only of NetBeans start-up, running NetBeans multiple times with the line switch
to stop it once the main window comes up. Since there is currently no extensive and functioning test
that will drive the NetBeans UI in memory consuming ways, these charts reflect startup performance only.
Note: The numbers may be wrong on Windows. There is currently a bug in the window system that
causes all of the components in the main window to dock themselves into new frames just prior to the
IDE shutting itself down. This does not happen with all sets of java lineswitches, but it likely
impacts the session time, since requesting new frames from the operating system is expensive.
Settings eliminated because they caused major garbage collections during startup
