It uses MySQL DB + Networking (TCP). Im currently using Nexus MemoryManager. I was wondering if I will have difference using FastMM4. Is there any differences? Stability, performance? Also I have a question about Memory Managers. Do they optimize the components itself? Or I have to recompile my components including FastMM or NexusMM file?

Stability should be the same: very stable. Performance wise: AFAIK Nexus is optimized for heavy multi-threaded use, so FastMM4 should be faster in your application - although I might not be the right person to give you an objective opinion. If your program doesn't juggle a lot of memory though, it is likely you may not see any difference in performance. The best advice would probably be to test it yourself.

The components uses whichever memory manager is installed, so you do not have to compile them for a specific memory manager. Usually all you need to do is to add the memory manager source file as the first unit in your project's .dpr file.

Stability wise there should be difference really. Performance wise, our MemManager is build to perform best in multithreaded apps on multi-proc machines. As desktop software is usually not of this kind FastMM will probably faster in this case. Not sure how much and some other things like code alignment might influence measures. Best is to try it out with your app i guess. Both will in almost all cases give any program using the default memory manager a major boost in performance and stability! -- Hannes Danzl [NexusDB Developer] Newsgroup archive at http://www.tamaracka.com/search.htm Back to top Hannes Danzl[NDD] Guest Posted: Fri Oct 07, 2005 10:38 am    Post subject: Re: FastMM4 or NexusMM3 Hannes Danzl[NDD] wrote: Quote: Jason wrote: Hello, I have a desktop software that runs in a 24/7 business.

I have had problems with nexus MM 3 in certain code loops with code optimizations turned on. I do not have problems with code optimizations turned off or when using FastMM4 or the stock RTLMM. -- Jason Southwell www.arcanatech.com Delphi & IntraWeb Components Consulting and Contracting Incident Based Support Back to top Bruce McGee Guest Posted: Fri Oct 07, 2005 5:58 pm    Post subject: Re: FastMM4 or NexusMM3 Jason wrote: Quote: But I like the TnMemoryStream of NexusMM... Do the Nexus classes require the Nexus memory manager? If not, there isn't any reason you can't just pick any memory manager and keep using TnMemoryStream. -- Regards, Bruce McGee Glooscap Software Back to top Pierre le Riche Guest Posted: Mon Oct 10, 2005 6:27 am    Post subject: Re: FastMM4 or NexusMM3 Hi Jason, Quote: Should I use Beta 4.35 in release of my software?
