Found a few things you can do to speed up Tangler with Firefox.

Go to your config in Firefox by typing about:config in the location box (where you type in the URL).

The first thing to change is:
network.http.max-persistent-connections-per-server

Scroll down till you find it, then double click and change the value to 8 ( note this was changed from 50 originally after the following discussion).

This will stop the problem with reverse ajax holding too many connections open to the server and thus limit the number of Tangler browser sessions you can have open at once.

For extra speed change:

network.http.pipelining  to true

network.http.pipelining.maxrequests to 50 

network.http.max-connections to 200 

network.http.max-connections-per-server to 5 

For those behind a proxy make sure you turn on:

 network.http.proxy.pipelining
 

I think that is making a difference

Thanks

I can't tell yet....

Will be back with a report soon 

I'm gonna give it a try too, Tangler is damn slow sometimes, it took me about 20 secs to open this tread...

ok done. we'll see how it goes

It is faster....

But still sticky when the notifier pops up 

Hard to say at this stage.

The main fix is to stop slowdowns if you open too many windows.

(slowdown = major stall)

In which case, the jury's still out on my end

hehe, I already had most of those values changed, if not to values quite as high as that based on separate "speed up firefox" advice, maybe thats why I haven't been feeling this slowness so much

what is annoying is when it gets stuck in a rut of showing the "error in loading messages" every time you open a topic and then miraculously being fixed when you click to try again (then a new topic brings a new error, and repeat)

also there can be a bit of lag in entering text - I'm quite fast on the keyboard and can occasionally leave the cursor a few words behind and have to wait for it to catch up so I can check I didn't mis-hit a key

For those behind a proxy make sure you turn on:

 network.http.proxy.pipelining

Mine read false. I changed it to true. Is this correct?

Wow. I feel I have truly reached a high level of geekdom today! 

Anyway to restore the default settings?

My FF is turning crasy since I did those modifications... 

Mine keeps freezing

Driving me nuts 

same here 

Oh, and it's not only when I use Tangler

the web pages stop to load.

I have to restart FF and then it works fine for 5 minutes and do it again.

Yeah!!

And when the notifier pops up, everything stops

I'm gonna restart comp now 

I reinstalled FF, but that's not enough because it keeps the config in memory somewhere...

rofl, there should be a disclaimer. Do it at your own risk.

Mine was freezing before I changed.

Now it doesn't

lol

I more or less switched back to the default settings. We will see if it fix the issue. 

Ok, it does freeze, but FAR less often

Before I was getting 10 second freezes on every page load

For a web developer it's like the world freezes 

in the config page anything you modified should be in bold and I'm pretty sure theres a "set to default" option for each one (maybe in the box that opens when you modify something)

It is not recommend changing  network.http.max-persistent-connections-per-server. 

Firing 50 conncurrent requests againast a single server is equivalent to a denial of service attack.  

the
default being 2 as recommended in the HTTP/1.1 specification
and it is

recommended to not set this beyond 10
if you do intend to raise the value.

otherwise your IP'll get blocked from most sites. 

maybe that's why my internet went crazy...

i edited the original post to be 8.

Re: I edited the original post to be 8....

Dangerous I think....unless you explicitly state that you have changed it!... Its one thing to change typo, or corrrect gramattical constructs retroactively (esp. to fix embarrasing letter transpositions in bear's names) but to change the complete meaning or context of a post when the stream of conversation below remains in tact  seems problematical to me...Do you  think changing it while highlighting the change in red/bold c/w a note of the date you changed it might be in order?

good idea. all done

It's possible to optimize for this on the serverside, too. An AJAX-heavy interface (like Tangler) can be served from mulitple domainnames to get around the limit on similtanous connections to a single domain name.

yeah, we've been playing around with that a little. on that long list.

guess kinda like meebo.com aye!!

You should be able to reset the preferences by running Firefox in Safe Mode (how to ) and changing the preferences back. (you could filter out the changed ones by typing User Set. (if it keeps crashing for some reason)
