Subject: Re: [PATCHv2 0/9] zswap: compressed swap caching

I forgot to include the link to the performance information we have
gathered on zswap from the first patchset.

Here are some addition performance metrics regarding the performance
improvements and I/O reductions that can be achieved using zswap as
measured by SPECjbb.

http://ibm.co/VCgHvM

These results include runs on x86 and new results on Power7+ with
hardware compression acceleration.

Thanks,
Seth
