Re: Expected speed of retrieve function (nstore retrieve)by BrowserUk (Pope)

When I load it back into Perl using 'retrieve' it takes > 5 minutes.
That is very slow.
Using a a 32-bit perl, nstoring a 40e6 (numeric) element array took 12 seconds and produces a 200MB file:
Retrieving it took 12 seconds and used 1.1GB peak:
A couple of possibilities:
Is the disk where you are storing it local? Heavily used? On its last legs?
Is loading the data (briefly requiring 1.1GB) moving you into swapping?
