We have a machine that doesn't do to bad. Our configuration is as follows:
75 MHz Pentium
64 Megs RAM
2 - 4 Gig Quantum Wide SCSI HDs (About to go to 4)
3Com 3C595 at 100Mbps
3 full feeds comming in split into 6 parts
9 full feeds going back out (Each feed split)
10-20 concurrent NNRP readers
Processor usage is usually around 17%, with an average load of 1.7-2.5. We
had problems with the HD's for a long time, but with the 2.0.0 kernel, we
have been able to run uptimes of 15-20 days with no HD errors. Normal was
about 9 days before.
Disk I/O is always the problem. This system ran for a year with a
486-80 powering it at <40% processor usage. Only reason we upgraded
to the P5 was for PCI. Large improvements were made by allowing
innd to process more articles prior to flushing them to disk. This
improved our throughput by an order of magnitude.
Our average propigation delay is ~.4 days, and we process ~240000 articles a
day. We are using only the Quantum 4 gig drives. We had started with Seagate
Barracuda, but they were failing every 9 months. The Quantums have been
operational for 12 months with no problems. Feel free to E-Mail us if you
want any more information.
: Is anyone out there in Linux-land running INN on an SMP machine underload?
: My current machine is servicing the following:
: 3500 nntp connections/day
: 50 nntp connections concurrent max
: 10 days discusiion groups
: 2 days binaries
: 1/2 day warez
: full usenet feed from Sprint and MCI (everything)
: On the following hardware:
: 133 MHz Pentium
: 96MB RAM
: 14GB HD
: NE2000 ethernet
: UnixWare 2.01
: 2 Adaptec 2940U SCSI Hosts
: I have tried moving this to an SMP system with 2 Pentium 133's under
: Solaris 2.5, UnixWare 2.01 and 2.1 without any success. The machine runs for
: a while and kernel panics under UnixWare and INN never ran correctly under
: Anyone have any suggestions for a Linux Solution?
: We are thinking about moving to a single 200Mhz Pentium Pro under UnixWare
: 2.01 with striping of the data over 4 4GB drives to increase through put,
: but if I could come up with something that would work with Linux that
: would be very cool.
: So net land anyone got a kick *news server on Linux?
