No, their are allocated on an as-needed basis for each thread. If a thread doesn't need to join anything, there will be no join buffer allocated. You can test that easily by setting them to really large values and noticing that your server doesn't run out of memory if your run INSERTs (for example). Jeremy -- Jeremy D.
