Apart from the slow hardware, the OS doesn't do any useful caching
at all. The stupidly low arbitrary limit on sockets limits the
number of simultaneous clients (assuming 4 connections per client,
which is very common, this could limit you to less than 25 clients
at once).

No, I'm not expecting 25 clients in a week, it is not a commercial
service, just a low interest one.

And the odd client from another country has said that their
downloads went fast enough. This was in spite of only getting the
inferior upload speed of a domestic ADSL connection.

They must be patient, then - normal ADSL has an upstream of around
25kB/sec with a prevailing wind. I get bored at that kind of speed :)

So it takes 20 sec to download a 500kB file, that's perfectly acceptable

Slow networking hardware. Copying data around many times before it
even leaves the machine for the client. Running a website from
anything other than a good leased line or co-location is going to
result in very bad performance. And I doubt many co-location
providers will accept a RiscPC or an Iyonix in one of their racks,
and if you have enough money for a leased line, you've got enough
money to spend 200 quid on a Unix box that will out-perform RISC OS
in every respect for web serving.

I don't think I have a leased line, whatever that might be.

A leased line is exactly as it name suggests, and is usually used for
reliable office internet connections.

It certainly achieved 100% security from Shields UP until I opened a
port for access to this server.

Sheilds UP is a joke, and run by a known moron and security
scare-monger. Don't use or trust it.

Again you are making statements without giving any evidence. This gives
me nothing to believe or check.


and something to sanitise requests (like a Squid in accelerator
mode in front of it) and your site's so trivial and unimportant
that hardly anybody will visit it.

Precisely. It is just to give access to some large documents that
are of interest to a minority of a minority.

Out of interest, why don't you host these on your website? (Which
appears to be served by Microsoft IIS.)

My website limit is only 200 MBytes and this little server is currently
holding 100 MBytes. I need so 70+ MBytes of space on the main website
when I do the three monthly update. So the main website cannot
accommodate all this minority of a minority stuff.

So for a year I have had an obscure yet secure and useful little
server. It costs me nothing. You have not given me any evidence
that does not say it will continue to do its job for another year.
I think that a certain wolf has been called here.

Well, it's cost you some electricity. It's difficult to find evidence for
things that are so instinctively obvious.

'Instinctively obvious'? That is not a way to explain anything to
anyone. I remember when I was being educated (all those years ago) that
the worst teachers were the brilliant ones for whom their subject was
'instinctively obvious' so that they simply could not explain it to
anyone else.

You also show a wide ignorance for the issues at hand, so I'm not sure
you're qualified to suggest that a wolf has been called.

But you are asserting that I will have all sorts of problems by using a
RISC OS machine as a server. So far you have produced no evidence to
support this and have included a load of meaningless phrases and insults
in the hope that you have covered up your failures to explain.

I think you are wasting everyone's time and so, for my peace of mind at
least, am putting you on a local kill-file.
