[infinispan-dev] Recommended Cluster Size for Replication Mode

[Faseela K]

Hi,

  With a 3 node cluster, even for "WRITES" my replication performance is better than distribution.
  That's why I came across this doubt.
  Could some body please clarify, why the behaviour is like this?

Thanks,
Faseela

There's no straight answer, it depends on the read/write ratio and the amount of data you store. 
Replication will always perform better for reads as it won't involve a remote call to get the data.
If you're mostly doing reads and your memory allows (replication is more memory consuming) then you should use replication.
If the amount of data increases or you're doing more writes, distribution is the way to go.
