ZODB / ZODB Performance / ZODB on SSD


Every database is performance limited by the hard drives. 

Historically relational databases were designed to load a bunch of identical records all at once.  Trees were expensive, particularly across record types.  On SSDs a database can afford to navigate the graph, and ZODB and python make it easy to do so.   In fact you can navigate the graph faster than ZEO can handle the data.  What a huge change to the world of software design.  

 Move ZODB to a Solid State Hard Drive, about 4 times more expensive, and you will no longer be limited by your hard drive persomance.   You will now be limited by the speed of the Pyrhon Process on the server.
