nodemap: also use persistent nodemap for manifest
The manifest as a different usage pattern than the changelog. First, while the
lookup in changelog are not garanteed to match, the lookup in the manifest
nodemap come from changelog and will exist in the manifest. In addition, looking
up a manifest almost always result in unpacking a manifest an operation that
rarely come cheap.
Nevertheless, using a persistent nodemap provide a significant gain for some
operations.
For our measurementw, we use `hg cat --rev REV FILE` on the our reference
mozilla-try. On this repository the persistent nodemap cache is about 29 MB in
side for a total store side of 11,988 MB
File with large history (file: b2g/config/gaia.json, revision: 195a1146daa0)
no optimisation: 0.358s
using mmap for index: 0.297s (-0.061s)
persistent nodemap for changelog only: 0.275s (-0.024s)
persistent nodemap for manifest too: 0.258s (-0.017s)
File with small history (file: .hgignore, revision: 195a1146daa0)
no optimisation: 0.377s
using mmap for index: 0.296s (-0.061s)
persistent nodemap for changelog only: 0.274s (-0.022s)
persistent nodemap for manifest too: 0.257s (-0.017s)
Same file but using a revision (8ba995b74e18) with a smaller manifest (3944829
bytes vs 10 bytes)
no optimisation: 0.192s (-0.185s)
using mmap for index: 0.131s (-0.061s)
persistent nodemap for changelog only: 0.106s (-0.025s)
persistent nodemap for manifest too: 0.087s (-0.019s)
