Indeed. Your data shows you're compressing less than 1.5k of data, which 
incidentally fits into a single TCP or UDP frame. So the gain in compression 
at level 0 (234 bytes versus 520) is not worth the time it takes, since it 
won't be transmitted faster.

Zstd's big avantage is the search algorithm. Since your data is so small, it's 
no surprise it's no better than LZ4. That result is the opposite of what I 
found when replacing Icecream's compression: the data transferred is in the 
order of megabytes, so the network time is the biggest contributor.

But thanks for the info, it's good to know.

PS: Have you tried LZO? That's what Icecream used before I changed.
