Subject: (7.20) I am not getting all the articles, but my feeder is sending a full feed

(From Carlos Castro <carlos@mci.net>)

Either your feeder is not keeping up with its feeders, or you are
not keeping up with the news flow.

Disk IO is probably the biggest news bottleneck. Usually a full feed
is more than a single Fast SCSI II disk can handle. Having 2 or more disks
for the spool is suggested in either a striped configuration (using ODS
for Solaris or MD for Linux) or a split spool. It is also recomended to
have the disks spread out over multiple controllers.

It is best to compile your system with MMAP if it can support it.

Run innd at a priority of -5 or -10 and see if it performs better.

Setting NICE_KIDS to 10 will also give innd more CPU on news servers
heavily loaded with many nntplinks and nnrps.

If you have many outgoing feeds you might want to keep the size of the
out.going files relatively small.... It takes quite a bit of effort to
write to the end of a very long file.
