} Is anyone else having a problem with expireover taking a long time
} to run with buffindexed?  On my server with 24G of cnfs spool and 4G

On my testing server(solaris2.5.1) it takes about 2 hours.

        all done Tue Oct 12 01:08:46 JST 1999
        expireover start Tue Oct 12 01:08:49 JST 1999
        expireover end Tue Oct 12 02:53:37 JST 1999

But I have another server(solaris2.5.1) which uses RAID5
for article and buffindexed spool and it takes too much
longer.

expire begin Tue Oct 12 03:18:21 JST 1999: (-v1 -z/usr/lib/news/log/expire.rm)
    Article lines processed  1956085
    Articles retained        1944815
    Entries expired            11270
    Articles dropped               0
    Old entries dropped        77654
    Old entries retained         149
expire end Tue Oct 12 03:26:35 JST 1999
        all done Tue Oct 12 03:26:35 JST 1999
        expireover start Tue Oct 12 03:26:35 JST 1999
        expireover end Tue Oct 12 10:23:36 JST 1999
lowmarkrenumber begin Tue Oct 12 10:23:56 JST 1999: (/usr/lib/news/log/expire.lowmark)
lowmarkrenumber end Tue Oct 12 10:24:05 JST 1999

} There are two major problems here... one is that this process seems
} inefficient.  Could we make it so that instead of re-writing the records,
} it makes modifications in-place?  So that expired article records are
} removed, but the remaining records are left in-place.

But buffindexed keeps room for expired article in the
case.  How do you think it will be purged?
