This popped up on reddit/r/programming yesterday, so I'll just copy my comment from over there:
How well does density [perform] when there's competition
for the I$ and L$? LZ4 in theory is slower than a number
of competitors (like snappy). However, LZ4 actually
handily outperforms them when put into a "live" situations
where it's running as a service alongside the 'real'
program.
The size of the in-memory data-structures is the real Achille's heal of most of the contenders to LZ4 I've seen.
- azinman2 12y agoInteresting. I've just been a casual observer to these types of things and haven't really considered total memory used but that's a big issue on devices like mobile, or even server environments where there many be many jobs concurrently. It's too bad that the Squash benchmark, linked in the github repo, doesn't have total peak memory usage. Do you know what the best contenders are as far as that's concerned?
- thechao 12y agoThe last time I researched this, to sufficient depth, was about 3 years ago. LZ4 was, hands down, the winner---nothing was even close.
