Use BufferPool instead of creating and destroying ByteBuffers

[viswamy]

Creating and destroying byte buffers in high load systems where GC pauses are considered very critical is an undesired scenario. I am creating this jira ticket to track an efficient implementation of buffer pool mechanism in which buffers can be reused over time which should reduce the memory pressure inside JVM. What do you think? Thanks!

Looks like a good idea. Do you want to implement it?:)

There are 3 open PRs that touch on the subject of memory usage: #184 , #195 , #35
