on 64 bit server very slow work

[Serg]

server win2003 -64 bit (opteron)+ Oracle 10.2.0.1
all new patched. DOA 4.0.7 - delphi 6 and 2006
very slow work (stop periodical, pause -5-10s , after go.. etc...) on 32 bit oracle and 32 bit Win - ok.
64 bit server and BDE - ok.

When exactly is it slow? When connecting, disconnecting, executing queries, ...?

 

[Serg]

for exampe:
3 table ( 2 conn master-detail)
scroll on record first table
20-25 record ok... pause(10-15 sec)
after scroll ok (25-30 rec) after pause..
always pause before change direct scroll.
the same example on 32 bit win and 32 bit oracle
without effect.
the same programm on BDE - ok.

I'm not sure what could cause this. What happens if you increase the ReadBuffer property of the dataset from 25 to 100?

thanks. readbuffer=100 and no problem
