Just be careful using any proxy-based solutions since the browser will change it's connection and request logic when going through a proxy (not sure with...
Hi Ralph, i think your experment is very helpful for synthetic labour testing. But you need to be sure that the speed you are going to measure only emulates...
correction.... need to be aware.... and notneed to be sure... sorry ... Von: heiko specht <specht_heiko@...> An: exceptional-performance@yahoogroups.com ...
Hi Heiko, I am aware of the issues you described. But measuring the performance like it is experienced by our customers is hard, because the data has still a...
There are a couple approaches to this. To answer your question directly, if you want a WAN simulator for "in the lab" use there's plenty of those. Shunra's VE...
Oh, I can't forget Anue Systems as another WAN emulator, they're a new kid on the block so are probably a good bit more affordable than Shunra. But those may...
Yeah, we use wildcard certs and it's more expensive but not prohibitive (especially if you don't go with Verisign - we use them because our business folks like...
I do want to note that the whole hostname/domainname thing is a huge thorn in the side of Web folks. Some technologies like cookies work at the domain level....
There's a setting in Internet Explorer's advanced options called "enable http 1.1 through proxy connections" - this is important to helping Charles behave more...
Hey everyone, I have been working hard on implementing the performance enhancements suggested in the YSlow plugin for FF. My first question is about Etags it...
... The seed value should be the same on all servers, but for most cases, that makes your ETags no different from the Last-Modified time, so it does not have...
Two parallel connections for the sprites is actually worse than having it as one large sprite over a single connection. The multiple connections help hide the...
On my web page there are 5 js files with the total size of 200k When I look at the http headers, it is showing 304 status code if I refresh the page But Yslow...
I'm playing around with using mod_expires under Apache 2.2. I've never used Expires before, but I'm seeing some weird things happening. When I browse to a page...
The guys at Aptimize <http://www.getrpo.com/> have stood up an instance of pagetest in New Zealand for the public to use at http://www.webpagetest.org.nz...
Patrick / Aptimize, Wow! Thank you for a great tool. Is there information available on the steps required to put a pagetest server in place? Also, is there an...
Ping me offline (PatMeenan@...) if you're interested in standing up an instance (either for public consumption or for testing inside of your firewall). I...
Pat, Again, thank you for a great tool. I especially like the start render and document complete bars in the waterfall. I can see using this alongside Firebug,...
We had a spare system lying around so I loaded it up with IE8 beta 2 for public testing (http://www.webpagetest.org <http://www.webpagetest.org> ). With the...

You really can't rely on those numbers. More important is the response time that a "real" user sees. On Gomez' homepage they have a free test app that will...
So, with pagetest <http://www.webpagetest.org> having been up for 8 months now with close to 26,000 tests having been run I thought it would be worthwhile to...
That's interesting but too be honest I'm not totally shocked - the average user tends not to get deep (by choice or simply due to lack of access) into the kind...
I don't think it's restricted to the average user. Something like CNN.com actually has a dedicated group of SA's. Persistent connections are enabled by...
In larger organizations it is often still the case where the web developers do not have access to the production servers, or to their configuration - you'll...
