asked on Interbase client V6.0 faster then latest versions?
Hi experts!
I know that it is not good idea to ask a question about Interbase in this TA, but seems I'll get a best support here.
Recently I noticed that report preparation process of the same reports takes very different time on differnt client's computers. Explorations shows that they use different versions of IB client. After making some tests I noticed that the best timing can be achived with gds32.dll V6.0.1.0.
I build a test application and a database.
Database has a large table with next format
TESTTABLE
ID_PRIMARYKEY integer,
STR_DATA varchar(20),
FLT_DATA numeric 12.4
TS_DATA timestamp
Nothing unusual. It has 500,000 records.
Test application just calculates time of fetching all records from that table. Something like this:
Q.SQL.Add('select * from testtable');
while not Q.EOF do
begin
Q.Next;
....
end;
I ran different servers versions on different computers. Results doesn't depends from server version but very differ from gds32.dll version on client computer.
gds32.dll version 6.0.1.0 is 4x (!!!!) times faster then
6.0.1.6
6.5.0.28
7.0.0.206
Can somebody explain me what I did wrong? I can't beleave that it is real situation. Seems I missed something?
