DRH, I looked at the memory management code mem3.c. I noticed a mutex to protect allocations/deallocations and was wondering what the impact on performance to a multi threaded DB applicaiton would be?
Other memory allcation schemes seem to allow each thread to manage memory independently of the other threads. In other words, the thread would have a hook into its own memory pool and would not be blocked by any other threads memory requests. Some interesting memory managers include: Unfortunately the first has licensing requirements and the second is copyrighted, but available for Free. http://www.cs.umass.edu/~emery/hoard/screenshot.html http://www.garret.ru/~knizhnik/threadalloc/readme.html Regards, Ken
