If decimal depends on allocator performances, you should maybe try to
implement a freelist.

I don't understand. 2% slowdown is when you use calloc? Do you have the
same speed if you don't use calloc? According to my benchmarks, calloc is
slower if some bytes are modified later.

Is it really useful? Who need bytes(10**8) object?
Faster creation of bytearray(int) may be useful in real applications. I
really like bytearray and memoryview to avoid memory copies. |
