Lack of speed in network environments

[Guest]

Hi!
In network environments my Xailer applications slow down when two or more
clients use the apps.
Who has similar experiences?
How can I solve this problem?
Best regards, Timm.

Hello Timm

Timm,
it seems to be a known problem with the opportunistic locking feature of
windows when more than one client using sharing dbf's.
Take a look at this http://support.microsoft.com/kb/296264
or http://www.superbase.com/services_tech_ ... plocks.htm

Timm,
I belive that's normal. The performance reached when two users are connected
is the regular one. When only one user is connected the performance speed up
due to the "oportunistic lock" behaviour by windows. If you test your
program in other file-shared environment, like samba under linux, you'll get
always the same "slow speed", even with only one user connected, because
samba doesn't use the "oportunistic lock". I did the test few years ago.
BTW, this isn't caused by Xailer or [x]Harbour themself. It applies to any
software that opens files in shared mode.

Many thanks for your answers!
I will try to switch of "oportunistic lock" like explained in the article
Ingo pointed to.
It is strange, but I don´t have those speed problem with my FWH/xHarbour
apps.
Best regards, Timm.

Hello Timm, We had similar problems of speed when tables DBF were lodged
under a Windows server 2003 standart, since from Windows 2000 server,
Microsoft change the way to share flat archives. I am solved with diverse
patches and updates of the S.O. , he looks for the documentation in the
Microsoft page if that is your case. I hope that he serves to you as aid.
