Noted :) To be clear I only mentioned it as an acknowledgement that everyone didn't necessarily agree with what I was saying. > The main problem is not the syscall so much as Java insisting on > zeroing out any buffer you create, which is a big hit to performance > when you're allocating buffers for file i/o on each request instead of > just mmaping things. Re-using those buffers would be possible but > difficult; I think using mlockall to "fix" the mmap approach is more > promising. Ok, makes sense. -- / Peter Schuller
