The cached RepoImpl sets the cache to something bigger, but CacheStore just
used the default. For a sets of small repos plus 10.2 repo, playing with the
sqlite3 cache size changed writing (done during parsing) times:
default (2000) 30.122s
8000 0m25.415s
10000 24.443s
15000 23.567
20000 23.529
You can see the curve has an optimum at 10 M or 15 M (is it worth to use 5 mb
to save 1 more second?) but this value should depend on the amount of data
you write. It would be cool we could optimize this value on runtime depending
on the situation.
