>>Do VFP screen refreshes really run slower under Citrix Metaframe?

>>I've heard that because the controls are not Windows controls that screen updates are slow, but this is not my experience. My VFP app seems to paint screens as fast as Microsoft Access.

>>Has anyone run any actual benchmarks on this issue? If VFP is as fast as other tools or perhaps only very slightly slower I'm sure many other developers would happy to hear this.

>>Personally, I'm very satisfied with VFP performance under Citrix.

>I was extremely disappointed in performance with forms containing multiple grids. One trick is to lockscreen before starting a whole series of refreshs, and not unlock until all control refreshes complete.

It's even applicable to Windows machines with 16Mb RAM (e.g. if grids use Dynamic coloring).
