VNX-2 performance problems with block deduplication
Hey,
Is there already a fix for the performance problems that you get if you start block deduplication in a environment with a 69/31 % r/w ratio?
It lookslike the problems start if your write ratio is higher then 30 %.

There's some dedup enhancements listed in the block oe 05.33.006.5.096 that was recently released (March 9), but I don't think it's addressing your specific query.

There are still many issues with dedup. We had to (almost) completely stop using dedup due to huge performance issues and few other defects, few fixes are promised to Q3/2015.
