sorry a wrong file: Win32MutexPrivateData.h is missing
2006/6/27, Adrian Egli <[EMAIL PROTECTED]>:Hi Robert,
after walking trough micrsoft document, threads and many many test. i changed the mutex
and thread implementation:
i tested it at the moment just only on 2 machine. the dual core computer and my single
core application. i need held for testing many other's because it's very low level, and if the implementation isn't good, we walk into troubles. but the performance is much better no only on the dual core computer.
can you watch may changes ( mark be // ADI begin // adi end or only // ADI )
if you feel good, happy with the changes i will prepare a propre clean implemation
for release 1.1. (other's are also wellcome to test it)
regards
/adegli2006/6/26, Adrian Egli <[EMAIL PROTECTED]>:thanks robert,
at the moment i try to locate the real bottleneck. i know your changes ref/unref, but i don't feel that this would be the bottle neck i have at the moment. but i will try the cvs version. hopply it would run much faster.
i will inform you as soon as i have locate the bottleneck. if we have to make some changes, we can discuss it further.

cause a bottlneck then try the CVS version of the OSG, it doesn't used
thread safe ref/unref() as widely as it did before, reducing the
overhead of running multi-threaded signifincantly.
