I finished porting my old application written in clipper 5.2
I'm amazing about speed of HMG. It's especially evident when I run it from pendrive.
I am impressed!

Hello Marek,
Thanks a lot for this very interesting topic
Yes, HMG is many times faster. I didn't "convert" any old Clipper app to HMG. But, I converted many old Clipper apps to xHarbour+gtwvw and Harbour+gtwvg. I found amazing improvement of speed in both cases
, especially with Harbour it's excellent.
I made some add-on projects for my old Clipper and VFP (
) apps. In both cases I found improvement of speed. I was really surprised when found my HMG add on is faster than VFP!!!
With best regards.

That is not rare... the last years, VFP become a little fat and slow

I test with a file. Dbf to over 2.200.000 records and about 990M of size.
LOCATE command of HMG and FVP are equivalent. HMG slightly faster
VFP very slow compared to HMG in example
Code: Select all
use data alias data shared new readonly via "DBFCDX"
DO WHILE .NOT. EOF()
IF data->user == "ABC"
/* commands */
exit
ELSE
skip
ENDIF
ENDDO
or
EDIT EXTEND command in HMG very bad compared to the
BROWSE in VFP with large files
====================================
During calculation, the intermediate results show up window can display the error. Although the program still run. This affects only the display but not the program crashes

Hi All,
Very recently I was creating some reports with DBF (you may call it as "add on" project) for my old VFP app (writtein with VfP6, which has problems with Win7).
I couldn't check the exact time. But, as per my observation.
1. VFP's (VFP 6) embedded SQL is very fast.
2. HMG app is more flexible and robust.
3. Exporting data to Excel (OLE) is faster with HMG
I was also testing very small project with VB.Net 2010 Express Edition with a small table. User interface is outstanding, but it's very slow.
