Allocators Performance Comparison

Summary
In this article we'll talk about allocators performance. We take performance comparison of:
- AutoFreeAlloc
- ScopeAlloc
- APR Pools (Apache Portable Runtime)
- MT Allocator (GNU C++)
- Boost Pool (boost::pool)
- Boost ObjectPool (boost::object_pool)
- NewDelete (new/delete)
Because most of allocators focus to improve performance of small objects allocation, we only test to allocate small objects here.
Test Cases
Assume our task is to allocate 1000,000 integer objects. If each allocator allocates one integer object, we need 1000,000 allocators. If each allocator allocates 1000 integer objects, we need 1000 allocators. And if each allocator allocate 1000,000 integer objects, we only need one allocator. Our pseudo test code is like this:
for (int j = 0; j < NAlloc; ++j) { SomeAllocator alloc; for (int i = 0; i < PerAlloc; ++i) { Use alloc to allocate an int object; } Delete all int objects allocated by alloc; }
Here, PerAlloc means the number of integer objects allocated by ONE allocator. NAlloc means the number of allocator instances we need. And PerAlloc * NAlloc will be 1000,000.
Here is the source code for our test.
NOTE: In these tests we DISABLED APR Pools' multithread locks. If we enable it, APR Pools will be much slower.

Conclusion
ScopeAlloc has the best performance in any condition. And if we allocate enough objects, performance of AutoFreeAlloc is close to ScopeAlloc.
