Just thought I'd share this:
PCWeek April 26, 1999 (vol 16, no 17) starting on page 1 talks about
the new microsoft Windows 2000 adding an in-memory database "retrieving
it [data]from cache instead of from disk, said officials of the Remond,
Wash., company.". "``It's huge", said Jomo Moir, senior web
technologist at CBS MarketWatch.com, a financial Web site in San
Francisco, ...''.
AFAIK, a decent OS [linux and others], does disk caching at the OS
level. Maybe this needs to be advertized as a feature of MySQL on Linux
2.2.x ;-)
