==== syscall stats for supersmack ====
== conclusion ==
77% of calls are reads and half of those
are 4 byte reads. These reads are done from mysql client
library, as a part of some kind of handshake...
doing these reads in largel blocks will likelly have
a very large positive impact on performance.
