I did simple sequential puts to the cache. The latencies kept spiking
intermittently to 30ms or higher.
The test took about 30 minutes to load 1M records. I am using the s3 ip finder
for discovery.
I would expect 1-2 ms at max putting to a cache per request, but 30 ms seems a
little higher.
Are there best practices I should follow to tune the server and the client for
better latency?
