333mhz G3 happily opens 17 tabs (my default startup) and is quite
usable.  For the first 30 secs or so Firefox isn't usable.  When done
it's sucked 125meg and taken 3 mins of CPU.  After about 30 of those
cpu seconds you can easily swap from tab to tab.

OpenBSD 4.2 with what ever Firefox shipped in ports (2.0.0.6 maybe)
basically felt like it worked the same.

Is the PPC that much more efficient? :-)

I haven't really done any rigorous testing, and I probably don't
really need 1-2 GB for 20-30 tabs, but the above is what I currently
use. ((I don't really care, because I plan on wiping this PC soon
anyway, and I hope I'll be able to again use OpenBSD more.))
That said, my hunch is, PowerPC vs. x86 prolly hasn't much to do with
it. IMHO (a) Ubuntu is MUCH less hardware-efficient than OpenBSD, and
(b) I take it from your post that you're probably not using Flash -- I
think heavy Flash in multiple tabs (even though eg. videos are not
running concurrently) is probably the main culprit.
In a nutshell:

Flash. The FASTEST way to send **all** of your clock cycles to /dev/null.(TM)

(Yeah. That's about it. That, and incompetently written
s-sss-zzzloowww ECMAScript that uses polling and shit
**cough** Digg **cough**.)

To be honest, a further discussion of the performance issues seen with
Ubuntu/Flash/bad JavaScript is off-topic for an OpenBSD mailing list.
Feel free to email me off-list though. :) I might even get around to

The delay is most likely caused by the DNS requests for all the different  
advert sites.  My guess is that Firefox handles the DNS requests in order,  
using the same execution context for all tabs, waiting for each one before  
proceeding to the next.  Requesting an  record that does not exist (or  
trying to connect to the first four bytes of an IPv6-address) might very  
well cause an additional slowdown.

What you describe migth be actually a DNS related problem. 

If dilbert.com doesn't resolve well using your current NS/resolver
library combination, some applications might wait to receive an answer
or a time out for the previous queried addresses before processing the
next request(s).

This behaviour can be avoided using a asynchronous resolver
implementation - in this case the application wouldn't wait for a reply
before performing the next queries. 

AFAIK the OpenBSD resolver library is not asynchronous, someone please
correct me if I'm wrong here.

However, if you can reproduce the behaviour using another browser, Opera
comes to mind, then you can exclude Firefox from your list of suspects
and the next step would be changing the NS you are using at this moment.

A bit of background here :

Firefox can do  lookups (for IPv6 addresses) by default for
websites you visit. Some DNS servers don't like this sort of query
and, in stead of saying hey, I dont understand what you want, they
ignore you in the hope that you go away. Things time out on your end,
your system will do a A lookup and from there you can continue
browsing the website.

In the case of the dilbert site, this doesn't seem to be the case.
Apparantly, one of the NS'en is not responding to queries at all (nor
ICMP Echo Requests - it's probably down or disconnected from the net
temporarily). Your caching NS may be trying to contact this one
nameserver. It'll wait for the timeout and then try one of the other
NS'en. The problem is exacerbated by the fact that www.dilbert.com has
a TTL of 300 seconds, so your caching NS doesn't keep this record in
memory too long.

The problem is that the resolver in OpenBSD isn't reentrant. If it's
doing nameresolution, it'll not do another one in parallel. So while
you wait for www.dilbert.com to get resolved (which takes long because
of this timeout), you open a new tab, enter an address and your
machine will have to resolve that too, which gets queued up (doesn't
get handled in parallel), so the other tab also waits on
www.dilbert.com to get resolved.

You can test this hypothesis by going to a website by its IP address.
Try visiting http://129.128.5.191/ (http://www.openbsd.org/) while
you're waiting for www.dilbert.com to load. Visiting by IP should work
(as it doesn't require a DNS lookup).

  So I guess its the problem with the OpenBSD resolver.

If you're not able to code a parallel/reentrant DNS resolver for
OpenBSD (I'm not), then here's a possible partial workaround:

The Dilbert site carries heavy advertising. You can use the Ad Block
Plus Firefox Add-On to diable the ads. You may wonder how blocking
Ablobe Flush ads helps with a DNS resolution problem. Well, the reason
this works is that most ads these days are included from advertisement
agencies **which use their own domains**. So blocking these domains
not only saves you all that Flash garbage (which also incidentally
eats up clock cycles like candy), it also saves you from having to
look up the agencies' domain names in the first place. When I visit
Dilbert with ABP enabled, the following filters are actively blocking
flashvertisements:

*.247realmedia.com/RealMedia/ads/*
*.advertising.com/*
*.adsonar.com/*

So in case of dilbert.com, with an appropriate blocklist,
247realmedia.com, advertising.com and adsonar.com are never resolved =
no attempted IPv6 lookup attempt for them = less slowdown.

NB: As for the number of open tabs, Firefox 2.0.0.x is a real sieve
when it comes to memory. It leaks and leaks and leaks... The upcoming
Firefox 3 is reportedly going to be a major step forward, but I
haven't tried it yet.

The desktop machine I'm currently using runs Ubuntu, so this may or
may not be directly comparable, but in my experience Firefox 2.0.0.x
**can** still be used with 20 tabs spread over 6 windows -- IFF you
throw truckloads of RAM at it (e.g. 1-2GB),

Lemme think :

o It's not easy to solve properly
o It's not that big a deal
o It's something that takes time to do (right)
o Noone cares enough to fix it / other priorities

If this is a big deal to you, your patches will be welcomed on [EMAIL PROTECTED]
I'd even be happy to test 'em for you ;)

Cheers,

 I've been noticing a similar problem with Firefox on OpenBSD...

I've also experienced this problem, but was never able to reproduce it.
It would happen maybe once every month or two during normal web browsing
(which in my case means 5 or more tabs simultaneously open in Firefox).

It seems to be better, at least on osx.  I have a number of add-ons enabled,
and after a while, things slow down - I keep 15-30 tabs open at any one
time.  Using the nightlies I don't have as much issues as the 2.x series,
from a performance point of view.

I can't duplicate your problem on amd64-beta and version 2.0.0.12.


However, I have seen behavior similar to what you describe.  I don't
think it's an issue with the stub resolver, since I've not seen
this with any other application that is or runs on OpenBSD.  It is
very likely this is a bug in the firefox/mozilla code which I have
suspected before is DNS-related but could be so many other things
as well.

Could this be because of local caching and little new resolve attempts?
