deltas: set estimated compression upper bound to "3x" instead of "10x"
In pratice, we very rarely observer compression better than "3x" on manifest
deltas. Having a more aggressive estimate significantly helps our pathological
use case on a private repository. Here are a comparison of timings using
different upper bound.
Estimated compression | ø | ×10 | ×5 | ×3 |
timing | 14.11 | 2.61 | 1.96 | 1.53 |
We also tested the impact of this series on an array of public repositories.
This shown no impact in either size nor timing.
Full data set below for those interested.
