Hi Pavel and All,
I should say this patch is Awesome!
Overall i saw "> 30%" improvement at-least for most cases. The tests where done
with 32 Core Intel 128GB and SSD Drives.
For 4 Nodes i was able to do 100K Reads Per Sec with this patch, before (trunk)
it was less than 50K.
But i have to say it exposes other issues in the Storage Proxy layer...
For example i was noticing write failing silently without hints been stored
etc, I did some digging and it was not due to this patch though.

> Components: Core
> Reporter: Pavel Yaskevich

> I have been working on https://github.com/xedin/disruptor_thrift_server and
> consider it as stable and performant enough for integration with Cassandra.
> Proposed replacement can work in both on/off Heap modes (depending if JNA is
> available) and doesn't blindly reallocate things, which allows to resolve
> CASSANDRA-4265 as "Won't Fix".
