Benchmarks -- we test reading and writing random numbers up to 2^N
For write-tests:
FMT is (format stream "~x" val)
SAFE is (fastnumio:write-hex val)
UNSAFE is (fastnumio:scary-unsafe-write-hex val)
For read-tests:
READ is (read stream) where stream has sharp-prefixed numbers
like #xBEEF.
SAFE is (fastnumio:read-hex stream) where stream contains
whitespace-separated numbers like BEEF
You can run these benchmarks yourself, e.g.:
ccl < write-hex-benchmark.lsp
ccl < read-hex-benchmark.lsp (**NOTE**: writes to /dev/shm!!
edit first if you don't have one)
Results from compute-1-2: Intel(R) Core(TM) i7-3930K CPU @ 3.20GHz
Linux compute-1-2.local 2.6.32-431.el6.x86_64
Things to improve:
- Want unsafe version of read-hex on CCL
