Richard Eckart de Castilho commented on UIMA-4685:
--------------------------------------------------
I would guess this gets a lot faster if `-Duima.allow_duplicate_add_to_indexes`
( ALLOW_DUP_ADD_TO_INDEXES ) is specified (cf. FSIndexRepositoryImpl line 98ff
and FSIntArrayIndex line 101ff). If dups are not allowed and there are many
equal-but-not-identical FSes in the index, then the insert operation appears to
get very slow. For simple annotations that would e.g. be the case if there are
many annotations of the same type at the same offsets.

> Support different CAS serializations in CAS Editor. Some recent profiling
> revealed that, when opening a 35MB xmiCAS, the CAS Editor spends about 70% of
> its time for deserializing.
