My slowest form loads in 7 seconds on the avg. This is on three year old
hardware (lots of ram 4 gb) using openSUSE. The same form runs much faster
on windows XP around 4-5 second loads.
With that said I have most everything available from Dabo on the form. Twenty
nine bizobj's with lots of virtual fields, lots of joins, lots of parent
child and grandchild relations, etc.. I have almost every control available
from Dabo including the standard textboxes, date controls, check boxes, radio
controls, dropdown boxes, tab pages, popup dialogs that contain Checklist.
My point is the load time is reasonable. I have experimented with all sorts
of ways to improve the load time without any real success. I then decided to
test the load time against VFP. I did not have to write the VFP form from
scratch because my current project requires that I emulate a VFP form in
Dabo. IOW I created the Dabo form based on the VFP form. I found it was
not that different. VFP for a similar form took around 4-5 seconds (on
windows of course). In fact I discovered that I could get VFP to load even
slower if I wasn't careful.
I have thought about providing a splash screen while in the background loading
of wx, and other modules required took place. But I haven't done anything
about doing it.
