$ hg debugupgraderepo
(no feature deficiencies found in existing repository)
performing an upgrade with "--run" will make the following changes:
requirements
preserved: dotencode, fncache, generaldelta, revlogv1, sparserevlog, store
additional optimizations are available by specifying "--optimize <name>":
re-delta-parent
deltas within internal storage will be recalculated to choose an optimal base revision where this was not already done; the size of the repository may shrink and various operations may become faster; the first time this optimization is performed could slow down upgrade execution considerably; subsequent invocations should not run noticeably slower
re-delta-multibase
deltas within internal storage will be recalculated against multiple base revision and the smallest difference will be used; the size of the repository may shrink significantly when there are many merges; this optimization will slow down execution in proportion to the number of merges in the repository and the amount of files in the repository; this slow down should not be significant unless there are tens of thousands of files and thousands of merges
re-delta-all
deltas within internal storage will always be recalculated without reusing prior deltas; this will likely make execution run several times slower; this optimization is typically not needed
re-delta-fulladd
every revision will be re-added as if it was new content. It will go through the full storage mechanism giving extensions a chance to process it (eg. lfs). This is similar to "re-delta-all" but even slower since more logic is involved.

$ hg debugupgraderepo
repository lacks features recommended by current config options:
fncache
long and reserved filenames may not work correctly; repository performance is sub-optimal
dotencode
storage of filenames beginning with a period or space may not work correctly
generaldelta
deltas within internal storage are unable to choose optimal revisions; repository is larger and slower than it could be; interaction with other repositories may require extra network and CPU resources, making "hg push" and "hg pull" slower
sparserevlog
in order to limit disk reading and memory usage on older version, the span of a delta chain from its root to its end is limited, whatever the relevant data in this span. This can severly limit Mercurial ability to build good chain of delta resulting is much more storage space being taken and limit reusability of on disk delta during exchange.
performing an upgrade with "--run" will make the following changes:
requirements
preserved: revlogv1, store
added: dotencode, fncache, generaldelta, sparserevlog
fncache
repository will be more resilient to storing certain paths and performance of certain operations should be improved
dotencode
repository will be better able to store files beginning with a space or period
generaldelta
repository storage will be able to create optimal deltas; new repository data will be smaller and read times should decrease; interacting with other repositories using this storage model should require less network and CPU resources, making "hg push" and "hg pull" faster
sparserevlog
Revlog supports delta chain with more unused data between payload. These gaps will be skipped at read time. This allows for better delta chains, making a better compression and faster exchange with server.
