title: Any faster/reliable to allocate multiple small blocks rather than 1 big block
body: <p>I have a program where I allocate multiple buffers as a part of a receive queue to receive messages from a port (UDP protocol). Currently the buffers are not contiguous, but now I am considering making them contiguous so that I can easily patch them together if need be. Is it any less reliable/fast to request 1 large block of memory as opposed to repeatedly allocating smaller blocks.</p>
  
  <p>The total size I'm looking at is 1000 2KB buffers, so 2MB.</p>
  
  <p>And please, don't tell me I should use TCP; if I could I would.</p>
  
  <p>By the way I'm using c++ and compiling with VS2005.</p>
