  In my case, not really.  I only started doing the compression when an
internal tool (constructed along similar lines ad the application I
mentioned) became ludicrously large because of one module (containing
thousands of names [2]).  Compression brought that down to merely largish
size [3].

  Yes, but the "embedded system" I'm programming for is a server with gigs
of RAM and an insane number of (slowish) cores [4].

  You're welcome.

[1]	Footnote not included here

[2]	Yes, we have need to generate names of people when testing.

[3]	I didn't want to have to install additional data files to make
	testing easier.  Also, I didn't want to have to install anything, to
	make testing easier on systems we had limited access to.

[4]	64-core 64-bit SPARC architecture running about a gigahertz or so. A
	bit sluggish compared to more mondern hardware but it handles heavy
	loads like you wouldn't believe.

	At least, I *think* it has 64 cores.  I know it has more than what
	you can normally get on a desktop.
