Hi,
Here is a good news to delphi/maxdb users. Few days ago we were still
developping our projet with Borland Delphi 7 Pro. We were pleased by
MaxDB but were unable to understand some slowness :
- Connecting a user was quick but not instantaneous
- Getting 25000 rows was so slow we had to look for tips to improve
the application overall speed
- We couldn't understand why according to Win XP network monitor data
transfert was only using 10-15% of our available BW
This week we received our turbo delphi pro install disk. Beiing happy to
receive a new "toy" we tryed to compile our main app with that "new"
compiler. Awesome ! The app is now faster and the most important thing,
MaxDB interraction is too. They probably improved their ODBC layer.
Now :
- Connecting a new user is as fast as possible
- Getting those 25000 rows is not instantaneous but fast enough not to
disturb the user
- Data transfert is now using 50% of our available BW.
Conclusion and what we learnt about that story :
- MaxDB wasn't slow, our compiler was !
- Buying a new compiler can sometimes help you to save money (compare
the price of 2 licences to the price of engeneers spending days in
looking for ways to improve an app speed) !
- I don't want to advertize borland or MaxDB but as I use to read posts
in which people claim having speed problems I hope that one can give
them ideas. Whatever their programming language is.
Kind regards
Xavier
