It's 20K TPS on something that MySQL will only do 3.5 TPS.  The queries
must be much heavier than the ones PostgreSQL can get 200K+ on.  We'd
have to do a deeper analysis of the actual queries used to know exactly
how much heavier though.  They might be the type MySQL is usually faster
than PostgreSQL on (i.e. ones using simple operations and operators), or
they could be ones where PostgreSQL is usually faster than MySQL (i.e.
more complicated joins).  All I can tell you for sure if that they used
a query mix that makes MemSQL look much faster than MySQL.
