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
Solaris.

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?

I'm just runing it under a single CPU...

I don't suggest the 2940 series in general for linux, unless you really
use teh new Seagate UW HDs (40-70 transfer rate). The driver for linux
for it was backwards enginered. Else use the NCR825 SCSI-2 card (What I use).

For linux, I suggest: a custom built P5 133-200, tritonII chipet, 64MB
ram or more. New seagate UW HD's, a BusLogic BDT RAID controller (or a
NCR825 with compiled kernel option of md to set raid-0 emulation).
Ohh I have inn1.4-unoff4 running fine with -mpentium optionsin gcc :)

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)
        AHA2940W
        3Com 3C595 at 100Mbps
        Linux 2.0.0

        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.

Our observations:
        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.

                        Thanks
