Some perfomance benchmarks at 5.3 release cycle showed that the way nullfs 
works is suboptimal, also file backed memory devices are very slow, but I'm 
no developer so I can't explain you exactly why. Perhaps someone had a look 
at this in the meantime, I didn't do any tests since then but I also saw no 
commit log which indicates that people were working on that.
