Certainly they can. I can do it in this quick Python script, too:
import nntplib, time
t0 = time.clock()
srv = nntplib.NNTP("gargamel")
response, count, first, last, name = srv.group("comp.lang.python")
response, overview = srv.xover(first, last)
t1 = time.clock()
t = t1 - t0
print "I fetched overview data for %i articles in %f seconds." % (len(overview), t)
which results in:
"I fetched overview data for 20640 articles in 2.710000 seconds."
(My caching NNTP server is accessed via a 100 MBit LAN and it probably has all
overview data in memory).
