We were just looking at numbers from the NOM HTTP Parser benchmark and thought it would be a good idea to put together a similar one for a BITMAUL based parser. I had a hunch that LuaJIT would perform quite competitively

The result is the BITMAUL HTTP Parser Benchmark.

The results : 5.4 Gbps parsing speed on an old Core i3

We did the following

1. Read the test HTTP header from a text file (header.txt)
2. Save that header in a string S
3. Construct a SweepBuf over the string
4. Parse the request line into verb, uri, version
5. Parse every single field into a LUA table with { field-name , field-value }
6. Go to 3 , repeat 10Million times

The sample code and more details are available on - BITMAUL HTTP Parser Benchmark.
