Our application news/deletes objects that range widely in size. Perhaps due to this, we see that some of these calls are internally causing mmap() and munmap() to get invoked. mmap()/munmap() are taking 100s of microsecs and cumulatively, they are throwing off the real-time response of our application.
Are there techniques or other APIs to configure QNX from calling mmap/munmap? Assume we cannot get rid of the news/deletes nor afford to write to write our own memory manager.
Our application runs on QNX 6.2.1B
