HELP ! : DOS database softwares are 100 times slower with Windows XP on Pentium 4 machines in networks !
What a paradox to explain to our clients ! THEY DON’T UNDERSTAND NEITHER ME !
I am a French Engineer who developped specific professionnal softwares with B-Tree databases which run perfectly on small networks with a server (under Windows NT 4 Server) and 3-12 workstations under Windows 98, NT or XP. They don’t want to pay again for re-developped applications with « New » Windows 32 bits power tools ! ! like Windev
All programs are developped with Microsoft PDS (Basic compiler 7.0) and Powerbasic modules
My clients were very impressed by so fast access to databases and are quite satisfied with DELL DIMENSION 4100 machines 3 years old machines with only 64 Mo RAM and Pentium III 500 Mhz
Since they have to order new machines DELL DIMENSION 4500 or 8200 (Pentium 4 processor > 2 GHz, 256 Mo RAM or more) with Windows XP PRO, I thought that performances would be better ! But the result is 100 times slower ! ! ! especially on networks :
Of course, I verified all network cards drivers installed by DELL (3Com or PCI RealTek RTL8139 Family 10/100 Mhz
I made all Windows XP updates...
I made all optimize tips known on Windows XP (See http://www.hotline-pc.org/whistlerastucesxp.htm)
I spent hours with DELL Hot-Liners which can’t do anything (telling : it’a problem from Microsoft...Contact them, but DELL install OEM Microsoft Windows, so nobody want to help you !
Though I know that Pentium IV is a 64 bits processor and the « old » compiler BC is not optimized for it, I wonder about such bad performances with XP !
I reinstalled some machines with Windows 98 2nd edition and results are much better (but not so fast as old Pentium III 500 Mhz machines ! ! So the problem comes essentially from Windows XP network protocol managment ...
I really don’t understand why Windows XP is so slow on networks access (Sometimes I think that Microsoft did especially times loops inside ! !)
By the way, it was very easy to add a command such as : SUBST G : C:\DATA in autoexec.bat file to simulate a server on a single machine : Now, on Windows XP machines, I can’t do the same automatically when Windows start (with a batch file in the « start directory » or in the autoexec.nt file)
This command is accepted only in a CMD opened windows ! ! not in a batch file
You can do the « same » result by connecting a G : to a \DATA (with networks tools of Windows XP...but time access is 100 times slower ! !
If anybody knows a tip to realize this SUBST command in WINDOWS XP launching, thanks to tell me !
If you know how to optimize Windows XP for networks : PLEASE TELL ME
