swapfile size with XP
Message 1 in thread
Hi to all,
I've been testing my Qt-app on many Linux- and OS X boxes. Recently I started running in on XP and here I noticed that it takes extremely much swap space - at least 300 MB and sometimes up to 1 GB which why I'm experiencing serious performance problems under XP. On Linux and OS X all is fine.
Does anyone know why this could be the case and how to possibly solve it ?
Thanks in advance

Well, maybe your application leaks memory under some circuumstances. You
can only find out by getting a memory profiler and checking your
application. On Linux valgrind is pretty widely known, not sure wether
its available on windows as well.

It's not, but other memory profiling / verification tools do exist for
Windows. Google can help. They're usually not cheap.
VC++ has a primitive leak detector.
