Is it normal for Iris to be more or less unusably slow on an ARMX6?

Well, at times it is unusably slow even on my 4té2, sometimes when entering characters indeed, but certainly not always. I'll see if I can find a pattern.
I did discover however, that Iris consumes a lot of processor power (30 - 35%) when being idle. Not that it explains its slowness, but I'd like to report it somewhere. Does some sort of an Iris mailing list exist?
Judging by the Task Manager in browsers on other platforms, some web pages have a particularly high background load. Blocking ads can help a lot
there, although I don't think there's a way to run an adblocker on Iris?
A network-based one like a Pi-hole may be a good start though.
Perhaps disabling Javascript in Iris would be worth a shot to see if the
idle CPU usage decreases?
Can you get to the problematic page, then disable Javascript and see if it's still slow? Or does disabling JS mean you need to reload the page / restart the browser?

I don't think Eventbrite would work at all with Javascript disabled; I
can't get beyond the first page of the event with Netsurf.

It would be worth trying to correlate which website(s) were open at the
time. In web browsers there's no such thing as 'idle', because Javascript events are firing all the time doing things like animating web page elements (eg ads). It may be that particular sites are better or worse for this.

I've tried twice to book an event via Eventbrite; the text entry was at
less than 1 character per second (I think the site was running some kind
of JavaScript check on every single keypress), and when I eventually got
down to 'Select Order' after struggling to correct typos resulting from extreme delayed reaction, the site just timed out on an attempt to pay
by credit card - not the only time this has happened, although last time
it got further into the credit card check process before to all intents
and purposes freezing up....
At this point it has currently been attempting to open the next popup or whatever the action is supposed to be for the last ten minutes, and I
don't think it is going to get anywhere with it.

I've just had paly with the eventbright site, and buying a ticket, it
didn't seem any slower than any other site. The site does seem to have a
mass of chunky graphics which may be slowing things down. Doesn't appear
to be lots of animations etc.
Have you looked at how much memory is being used by Iris and associated
bits. Just looked at the tasks window and it using 100+K plus Shared Libraries over 116K and that while it is just sitting on the icon bar.
It will be your biggest application on your RISC OS machine.
You do not say which version of Iris you are using I am on v1.028
The ARMX6 is considered the minimum spac RISC OS computer for use with
Iris, faster machine like the Pi4 (4te2) running at 2 Ghz are better, but does depend a lot on the site and how much junk is being downloaded in the background from any given websites, the more tabs or Iris windows you have open the more speed can be impact.
It would be worth trying to correlate which website(s) were open at the
time. In web browsers there's no such thing as 'idle', because
Javascript events are firing all the time doing things like animating
web page elements (eg ads)

By the way, my version is 1.027. Where can we get the newer version?
By comparison: NetSurf doesn't claim any usage displaying those pages.
Not that it really matters. As soon as another program needs the full
power, Iris and its companions obediently shrink to 0%.
But since they do consume power when doing nothing noticeable, and
although an RPI is extremely power efficient, I prefer to run Iris only
when needed.

Go to the download link you will have on your start page, it came out
in May 2023, the main change I believe is adding Printing features.

Is this update not availble to all?
I am not one of the early subscribers. I merely bought it from the
!Store. All I can see doing that is the Apr2023 iteration which I already have.

It might depend on the link you have on your start page. There appears
to be two different links. I am not going to publish them here.
You could always email ROD asking if the v1.028 is available to download
as you obtained your link via PlingStore.
Iris claims between 18% and 52% of the processor usage (it's going up and down all the time), after just being loaded, so when no page has been displayed yet.
Displaying the Google search page, without any noticeable adds or
animations, claims around 40% processor usage, divided over WebKitNetworkProcess, WebKitWebProcess and Iris itself. The same is true
for the built in ROD start page. By comparison: NetSurf doesn't claim any usage displaying those pages.

Ta. Interestingly, the vers 1.027 I have on my FAST machine stiffs the machine when I quit Iris about 3 times out of 5. I've tried closing all
other running things before I shut Iris but seems to make no difference.
I can't fathom why this is happening. Nobody else seems to have reported
it happening to them.

I have seen this a couple of times in the past, usually where a page
has failed to load for some reason.
Found it was a stuck Webkit entry in Application tasks, that was still
trying to load the page in the background.
