title: Multithreaded Memory Allocators for C/C++
body: <p>I currently have heavily multi-threaded server application, and I'm shopping around for a good multi-threaded memory allocator.</p>
  
  <p>So far I'm torn between:</p>
  
  <ul>
  <li>Sun's umem</li>
  <li>Google's tcmalloc</li>
  <li>Intel's threading building blocks allocator</li>
  <li>Emery Berger's hoard</li>
  </ul>
  
  <p>From what I've found hoard might be the fastest, but I hadn't heard of it before today, so I'm skeptical if its really as good as it seems. Anyone have personal experience trying out these allocators?</p>
