Removing the + i gives:


  | spentTime UTF = 3696
  | spentTime UTF = 3587
  | spentTime UTF = 3699
  | spentTime UTF = 3672
  | spentTime UTF = 3806
  | spentTime PutSimpleString = 161
  | spentTime PutSimpleString = 142
  | spentTime PutSimpleString = 133
  | spentTime PutSimpleString = 148
  | spentTime PutSimpleString = 135
  | spentTime putString = 2972
  | spentTime putString = 2922
  | spentTime putString = 2967
  | spentTime putString = 2942
  | spentTime putString = 2905
  | spentTime putStringNewWay = 974
  | spentTime putStringNewWay = 937
  | spentTime putStringNewWay = 977
  | spentTime putStringNewWay = 955
  | spentTime putStringNewWay = 960
  | 

I also remove putNewString() since I didn't see the point of that.

Also you need to test the perf of reading. There's no point writing stuff you never read!

The point that putString is slower than putting the shorts in one by one, implies to me that the overhead is in the Netty ChannelBufferWrapper implementation.

If you look at the Netty ChannelBufferWrapper implementations you will see they do a lot of stuff on every put. So we need to minimise the amount of puts.
