Thanks in advance depends a lot on what your app does how much is down to your own coding and how much you can tweak that Changing memory manager will help sure, but, nothing can make up for code which dould do with optimzing -- Liz the Brit Delphi things I have released: http://www.xcalibur.co.uk/DelphiThings Back to top Mike Williams (TeamB) Guest Posted: Fri Dec 23, 2005 6:26 pm    Post subject: Re: How could I more speed in my app ?

If your application is slow you really need to measure the performance using a profiler to determine where the bottlenecks are. Sure, changing the memory manager might help but if it did how would you know without measuring it? -- -Mike (TeamB) Back to top Mike Williams (TeamB) Guest Posted: Fri Dec 23, 2005 7:13 pm    Post subject: Re: How could I more speed in my app ?

Thanks in advance You need to analyse where the slow parts of your application are. Disk, memory, network, CPU? The best way is usually to redesign that part of your application which is slowing things up. Don't know which part? Perhaps Eric Grange's Sampling Profiler can help: http://glscene.sourceforge.net/misc/SamplingProfiler.zip I've found this profiler most effective - both as a rough tool (when I discovered a routine which was much slower than expected), and for fine tuning - improving individual lines of code. But your brain is probably the best optimisation tool you have! David Back to top JEM Guest Posted: Fri Dec 23, 2005 7:47 pm    Post subject: Re: How could I more speed in my app ?

Two words - intelligent design. ;-) Seriously, the best hope you have of getting more speed and reliability in your application is to use a profiler and test, test, test..

"Carlos" <ij@i.com> wrote Quote: All my forms are created at runtime Don't do anything when you start the program, other than displaying the main form (bypass all on create activities, opening files, creating forms, as much as you can so that the program will load). Unless you are loading the executable from a network, load time should not be too different than starting a "no code" delphi project one that only displays form1. Then start enabling opening procedures one at a time, until you find out the culprit(s). Many times, especially if you are loading a huge executable from the network, the slowness is unavoidable. If that's the case, just design a good looking splash form. Robert Back to top Mike Shkolnik Guest Posted: Fri Dec 23, 2005 10:12 pm    Post subject: Re: How could I more speed in my app ? Do you use the database? Maybe connection is slow or you fetch the large recordsets from server to client. -- With best regards, Mike Shkolnik E-mail: [email]mshkolnik (AT) scalabium (DOT) com[/email] WEB: http://www.scalabium.com "Carlos" <ij@i.com> wrote Quote: Hello, I would like get more speed in my application.

Lots of good advice here, but if you are using anything other than Delphi 2006 definitely do change the memory manager. I've gotten a speed increase of 30% by switching to FastMM4 from the d5 default. Your milage will vary of course but that's pretty good for one line of code.

Two words - intelligent design. ;-) Seriously, the best hope you have of getting more speed and reliability in your application is to use a profiler and test, test, test.. And think carefully about any algorithm that uses nested loops. Eons ago I remember an article on speeding up a program. The problem being worked on was the 8-queens problem. How many solutions are there for various board sizes? I blew away their best tuned solution by a mile by constructing a solution that never once looked at the board. While it maintained a copy of the board that was strictly for display purposes--the actual algorithm worked by keeping track of which axes were already blocked. A 2D loop was replaced with three array lookups. Back to top JEM Guest Posted: Sat Dec 24, 2005 9:17 pm    Post subject: Re: How could I more speed in my app ?
