Two comments.
Context switches are of course much cheaper then loading a JVM. No argument
there. The point is that the JVM is loaded once for each connection (when
the connection makes the first call to a java function). Millions of calls
may follow that reuses the same JVM. Each of those calls will suffer from
context switches if the JVM is remote. A 1 to a million (or more) ratio is
in fact very likey when function calls are used in predicates and/or
projections of selects on larger tables.
Regarding C++, as I said, no big deal. I'll change it for the reasons
mentioned before I release my first cut.
Thanks,
