Using DB to cache METARs ?

[Phil P. <phi...@sw...>]

Supposedly using a DB of some kind to cache METARs makes things faster.
Is there any to DEBUG this?
Because I'm finding it's simply not any faster at all.

(and FYI I don't have shell access to the machine, so any debug will 
have to be via PHP scripting or something)

Page generation takes anywhere from 1.4 to 1.9 seconds.
When I use NO DB, *and* when I use Sleepycat DB3.

The METAR was generated less than 1 hour ago, so after I've refreshed 
the page a couple of times, in theory the data should be in the 
database, right?

Lemme know if you have any ideas where I can look to fit it and get the 
caching working. As obviously ~1.5 seconds per page is simply not 
accceptable.

Thanks
