Python script too rough tool to measure decoding performance on short strings. To do this I used C.
The benchmark scheme is as follows. Taken a big enough chunk of memory to reduce effect of processor cache. This area is splitted into many pieces with the same offset over long aligned block. Then measured a time of decoding all pieces of a certain size with a certain offset. Calculated an average time (ms) and decoding speed (MB/s).
Run benchmark:
gcc -Wall -O3 -I Include/ -I . -Xlinker -export-dynamic decode_ascii_bench.c libpython3.3m.a -lpthread -ldl -lutil -lm -lrt -o decode_ascii_bench && ./decode_ascii_bench |
