I know.

Yes it is. It is a big deal. Let me ask you something:

would you give up 3% interest on an investment?
would you give 3% of a year extra to your employer
instead of holidays? That's about 11 days of holidays,
which is two whole weeks .. around here that's the whole
of your Xmas holdiday .. and over half your total holidays.

You might think the comparison is unfair.
But software systems compete on margins, like
anything else. 3% off an overhead is a good improvement.
Get it fast enough and the case for recoding
in C -- or even assembler -- will diminish.
