r39527 | ==================================== | ||
Test delta choice with sparse revlog | ||||
==================================== | ||||
Sparse-revlog usually shows the most gain on Manifest. However, it is simpler | ||||
to general an appropriate file, so we test with a single file instead. The | ||||
goal is to observe intermediate snapshot being created. | ||||
We need a large enough file. Part of the content needs to be replaced | ||||
repeatedly while some of it changes rarely. | ||||
