I ran 2 IspnPerfTest processes on my local box with numOwners=2 (no L1
cache). I guess that roughly half of the calls go to the local node, and
there the cost of withFlags() is not amortized by the network round trip.
All the reads are local as both nodes own all the data in this setup. Writes will involve
RPCs, though.
Even for local caches, the 10x performance degradation from using the flags is way too
much, there must be something else at stake. If you profile it we can take a look.
