Henry pointed out that there is not much you can do to newsrun to
speed it up without breaking it's robustness.  I agree, but you
can tweek it a bit for added performence.  The first and biggest is
to comment out the  c7decode lines if you never expect to get encoded
news.  The other thing I have done which helps if you get many small
batches (ie from a once a minute NNTP sender) is to rewrite 'spacefor'
and 'sizeof' into C if you can.  Both are trivial to write but you
may need a statfs() system call for the former.  This reduces the
numerous ls, df, and awk calls.

I do agree that C news is considerably faster, our Sun-2 had just stepped
over the brink and was not able to keep up with the volume, with C news
it has been given a reprise.
