Speed issues with BDE+Informix

I have application which has been developed on Delphi 2.x with Informix Standard engine 7.x database. I am using BDE to connect the client to the server (Database). Most of the queries take a long time to fetch the data. But the same queries if fired from the server goes thru in a split of a second. I have checked & tested the network, informix, OS settings. All seem to be correct. Is there any way to speed up this. ???

hmm, this is just a thought!

Way back before the dinos I was programing MS Access 2.0 and using an SQL server..I had the exact same problem, until I realised that the I was not using "Pass through" SQL - this means that the program that handles the client end must translate or atleast preempt it before passing it to the SQL server..could this be your problem ?

Try out the Informix ODBC Drivers from Merant. It processes Informix queries about twice as quick as Delphi's native Informix driver.

Queries also need to be optimised so that they range over the smallest subset of data. The Informix driver seems to perform the query locally, performing more processing on the local computer rather than the server. The more you can stuff into your "Where" clause the better.
