Hi
I have a problem where mongrel on vista is veeeery slow. I’ve
confirmed in with two different computers running Vista.
Same code has no problem on XP or Linux.
Basically on both of my Vista instals, looking at “net” section of
firefox, I can see that it appears to take 1sec between each asset.
This seems really nuts. Has anyone else managed to get mongrel working
nicely with vista ?
Any help much appreciated.

What does the log show when it handles a request? What version of ruby
are you running on Vista? Does it differ from that installed on the
other 2 OSes?
If it’s just a ruby quirk, lighttpd & webrick should run pretty
smoothly. I’m guessing this may be some kind of threading problem?
[I’m assuming you’re not using mongrel cluster].
I’m also guessing you’re just using RoR in Vista for dev work or nerd
points, not as a production environment 
so maybe falling back on
lighty for a while wouldn’t do any harm?
Well it seems v slow regardless of the version of ruby (tried a
couple).
Additionally - it seems that its only firefox that causes problems.
IE7 is fine.
FF starts ok and it seems to get progressively worse.

The problem’s right in front of you: Vista.
Sorry, I just couldn’t help myself. I started developing Rails apps on a
Vista box about three weeks ago and the experience has been nothing shy
of tortuous.
Anywho, I hope you get your issues resolved. Maybe try Leopard? =)
In answer to your questions:

not really - just the migration pain and the ‘im used to mongrel’
part.
thanks for the feedback

well it was all working well on XP and really it only seems to be
firefox on mongrel on vista that works badly.
so it’s nearly there !!! but not quite !!

How is firefox performing with other websites hosted on the local
machine? maybe it’s a resolving localhost issue? What are connection
settings in Firefox? Are you behind a corporate proxy? Is firefox going
out to that proxy then back to the local machine (i.e. do you need to
enable ignoring of proxy for localhost).

I’ve just noticed similar problems (I think). This is very wierd. I’m
running Vista x64 fully updated.
Works OK with:
Firefox, Webrick
IE, Webrick or Mongrel
NOT OK with:
Firefox, Mongrel
Thing is before I updated to the latest preview release of Rails
everything was running fine. Now however, long after mongrel has
finished firefox is still churning away.
I might switch back to a previous version of Rails to see if that really
is the problem as I’ve made a number of other changes but it’s happening
on two different Rails apps I’m developing.
What happens if you spoof the FF user agent as, say, IE7?
If you open another tab in FF and go to about:config, is
“network.http.pipelining” set to true? if it is, try turning this off
or reduce the maxrequests.
Have you tried connecting to your app from a gecko-based browser on a
remote machine?
I’m just throwing ideas out here…!
The same app works ok with webrick in Firefox
Connection settings are out of the box install. No proxies.
Very odd.

Tried the user agent - nope
Pipelining is not enabled
Haven’t tried the remote machine idea yet.
What a weird problem. Vista - Mongrel - Firefox.
Hey Weepy were you using the x64 version of Vista? That gives me an
idea. I’ll try some other browsers (Opera perhaps) and also Firefox x64.
And I can’t remember which version of IE I tried so I’ll check out both
32/64 bit versions.
Thanks for the good ideas chris – unfortunately I caved in, flattened
and installed XP !
Ill try them on another machine if i get a chance 
Hi Phil
I was on 32 bit
What a weird problem. Vista - Mongrel - Firefox.
Yes !!
I notice that mongrel 1.0.2 is out - perhaps this fixes ? though i
cant see it in the changelist.

also i was using rails 1.2.5 and have seen the same problem with 1.2.3
on another computer.

does it work with FF on a different computer, acccessing mongrel there
on the local computer?
If not then use wireshark to see when the packets are coming in–i.e.
“is this FF or Mongrel that is erring”
also check the logs to see if anything looks suspiciously large, and, as
a last resort, look into rails/ruby profilers maybe.

The problem was with static resources - so I guess this is a mongrel
problem rather than a rails problem.

I did try 1.0.2 but the problem remained.
Thanks for suggestions Roger. I’ll look into it.
So I then wonder…
was IE requesting different files? Or the same files but then rendering
before the static files entered?
Why the difference between IE and FF? Interesting.

IE will try to pre-render the page while it’s downloading, so a bad
resource isn’t as noticeable. Firefox waits for the complete doc
before rendering certain elements such as tables and such.

no
IE will try to pre-render the page while it’s downloading, so a bad resource isn’t as noticeable.
We’re talking 1 second per resource with say 40 resources. They seem
to load sequentially so the whole page load takes ~40s !
