Hello All,

My customers experience s drastical slow-down in performace of my Xbase++ application.
It makes no diffrence is compiled with 1.9 or 2.0

The dialog contains 830+ xbase parts of all kinds
Lots of Tab pages, browses, buttons, radio buttons, groupboxes ans check boxes.
All is build using Express++

To me there is no logical explanation fior this.
I have 4 Computers to my displosal. Below a bench mark:

Same application, same Xbase++ version, virtualy no data-access.
Switching processors do not have noticable changes.

Windows 10 Amd Phenon II x4 955 3.2 GHz 12Gb = 14 seconds.
Windows 10 Intel i7 4810-MQ 2.8Ghz 8Gb = 4 seconds
Windows 10 AMD 6400 Six core 3.5 GHz 8Gb = 6.5 seconds
Windows Vista Pentium Dual core CPU E5200 2.5Ghz 4Gb = 4.5 Seconds.  This last PC is 9.5 years old !!.

Regards
Jack Duijf

Hi Jack...

Shot in the dark here but have you tried disabling the AV software on
the 14.5 second box?

Regards... Jonathan

I've heard about problem with "Windows Defender" and it is enabled by
default on Windows 10.

A trick I always use to avoid screen flickering and speed up process is

oDlg := New empty window...
oDlg:create()
oDlg:LockUpdate(.T.)
... Create every controls
oDlg:LockUpdate(.F.)
oDlg:DrawingArea:InvalidateRect()

This make an empty window show up, then every controls appears at once.

Hi Jack,

I discovered this if the databases are on a network device, and the 
drive is not mapped to a drive letter. UNC path seems to be slower than 
a mapped drive.

what Grafic Card ? does it use a AGP ? Original or M$ Driver ?
with 12GB you need more than 2 RAM Slots ... try to use only 2 RAM Slots ( 
no RAM Dual Mode )

Hello All,

Thank you all for your input.
It tuns out the video driver is of some influence.
If i disable the ATI Radeon HD 4250 and ATI Radeon HD 4300/4500 series, and go back to simple screen device, i gain 3 to 4 seconds.

I started Windows in protected mode, but then i can not start my application.

If i find the time, i wil create a test application 

Regards,
Jack Duijf
