In Topic: TNextGrid.ClearRows very slow

Boki,

so you can reproduce it? No additional stuff. Simply creating a new empty VCL application, placing a grid on a form, adding e.g. 10.000 rows with 60 text columns and then calling ClearRows. ClearRows happens in a BeginUpdate/EndUpdate block. I can send you a Delphi 2010 demo application if you wish.

I'm using Delphi 2010 Professional and NextGrid 5. Not sure about the exact build number of NextGrid.

Doesn't look to be specific to VMWare, but rather the big difference is when running outside the Delphi IDE or not. When running the mentioned scenario/exe in the Delphi IDE, it is terribly slow. Running the test application outside of Delphi, it is really fast. Any ideas?

Of course, I'm using a BeginUpdate/EndUpdate block.

VMWare 10 Workstation seems to be the problem. I'm running my dev environment in VMWare. Clearing a grid with ~ 10000 rows while running the executable in VMWare takes ~ 40 seconds. Running that test on the host directly, clearing is nearly instantaneous.

Ever seen something like that?
