There are more major performance improvements between 0.92.1 and 0.94.16.1
releases than I can count on two hands. I think the help we can provide you
since you cannot change software versions the entire year will be quite
limited. 0.94 is a drop-in replacement for 0.92. While you cannot do a
rolling upgrade (see http://hbase.apache.org/upgrading.html#upgrade0.94),
there won't be a data migration step. I'd suggest trying an upgrade from
0.92.1 to 0.94.16.1 in a dev environment to see if it's at all an option
for you. I think we would all recommend this course of action.
