I played around with different file and chunk sizes using attached benchmark script. After several test runs I think 1024 * 16 would be the biggest win without losing too many μs on small seeks. You can find my benchmark output here: https://gist.github.com/tiwilliam/11273483 My test data was generated with following commands: dd if=/dev/random of=10K bs=1024 count=10 dd if=/dev/random of=1M bs=1024 count=1000 dd if=/dev/random of=5M bs=1024 count=5000 dd if=/dev/random of=100M bs=1024 count=100000 dd if=/dev/random of=1000M bs=1024 count=1000000 gzip 10K 1M 5M 100M 1000M |
