> As a result of studying the flamegraphs, it was discovered that when sending
> messages to yourself there are non-optimal sections of code:
> # Initializing *java.net.InetSocketAddress* spends a lot of time for
> *org.apache.ignite.internal.network.DefaultMessagingService#isSelf*.
> # Iterating through handlers in
> *org.apache.ignite.internal.network.DefaultMessagingService#sendToSelf*
> creates an unnecessary iterator.
> It would also be good to optimize the obviously non-optimal places:
> *
> *org.apache.ignite.internal.network.serialization.PerSessionSerializationService#createClassDescriptorsMessages*
