Memory usage is dependent on - libraries used - memory allocated - stack requested - whether large pages are being used
However, in most situations the memory footprint should not be an issue - since only the memory that is used will be given to the application. You can use prstat to look at memory footprint - check the RSS column. In terms of performance tuning, there are plenty of resources at: http://developers.sun.com/sunstudio/articles/index.jsp http://developers.sun.com/solaris/reference/techart/index.jsp Assuming you already have Sun Studio 12 (free download from http://developers.sun.com/sunstudio/ ) Then you should look into using the Performance Analyzer to profile your application. http://developers.sun.com/sunstudio/analyzer_index.html Then take a look at changing the compiler flags: http://developers.sun.com/sunstudio/articles/options.html You may also want to take a look at the CMT Developer Tools: ATS does automatic performance tuning of applications: http://cooltools.sunsource.net/ats and spot does a detailed html report on application performance: http://cooltools.sunsource.net/spot You can download the for both Sun Studio 11 and Sun Studio 12 from: http://cooltools.sunsource.net/cmtdt/install.html Regards, Darryl http://blogs.sun.com/d/ verma wrote: > Dear All, > > Could any one help me how I can decreases memory using by a particular > application . > is there any magic of using run time linker apart from lazy loading etc for > memory performance. > > Please also help me how I can reduce an application run time(startup time as > well execution time) > > > Thanks & Regards > > > This message posted from opensolaris.org > _______________________________________________ > tools-linking mailing list > tools-linking at opensolaris.org
