I am facing a kind of scaling mystery while using register interest.

Use-case is basic :
N publishers publishing into a geode cluster w/ M subscribers using
register_interest (regexp).

in our case,
- M can be up to 1000 process (not threads)
- Publisher throughput is about 50k requests per sec on 200k keys
- Volume is small (around 10GB)

We observe put (from publisher point of view) latency diverging with the
number of consumers, up to 10 sec (p99) and 5 sec (p50)
AFAIR, the key is evaluated on the put (sync).

Any ideas , customisation of the configuration you can advice?

Regards.
