Anton Vinogradov commented on IGNITE-1093:
------------------------------------------
Found and fixed reason of GC pauses. At entry eviction new
GridCacheObsoleteEntryExtras created for each entry. This cause GC pauses at
newGen overflow.
Fixed by using pregenerated GridCacheObsoleteEntryExtras instance, one for all
partition's entries.
> Rebalancing with default parameters is very slow
