Populating choose list performance: Windows vs. LInux [message #1824409]

Hi everyone,

I have a plugin that runs on Windows and Linux. The plugin presents the end-user with a choice list that has 40,000 items (this is not a typo and don't ask me why this is so, our application does it because the data in the choice list is customer data driven). On Windows, it takes about 10 sec for the UI to render and make available this choice list, but on Linux it takes 10 min. I know the underlying architecture is different, but I never expected to see such a huge delta. Any idea why?

Thanks,

-- George

Hi,

It is very hard to guess where a performance issues comes from. The best answer you will get by using a profiling tool, some clues you can get by taking samples of the stack trace [1].

Best way to get some support on tracing down the issue is reporting a bug on Platform-UI or Platform-SWT. Attach a (minimal) example plugin to show the problem, and attach your profiling results.
