Comment (by ryandesign):

 Replying to [comment:4 mojca]:
 > Curl might be as fast as is gets, but it would be even faster if we had
 a local database with all available files.

 Maybe. Seems like something that could easily get out of sync. And how
 much time would this save? How quickly can we do a (SQLite?) database
 query? The curl check takes about 0.05 seconds, and it looks like we could
 cut that to 0.02 by using http instead of https.

 > I don't know enough about Tcl to be able to tell how to avoid re-
 initializing everything every single time.

 I meant: instead of running archive-path.tcl and
 port_binary_distributable.tcl and portgroups.tcl and supported-archs.tcl
 for each subport, could we combine those into a single script? Move some
 of the logic from bash into Tcl? Even though we don't currently run all
 four scripts for all ports (some are run conditionally), I feel like
 probably most of the time is spent in initialization, such that combining
 them into a single script that does all four tasks would still be faster.
