tabstrip component loads slowly

Hi, Folks --

I am using a third-party tabstrip component in the site that I'm developing. It's loading slowly on initial access and refresh, but not when I navigate to another page that uses the same component (from the same master page). If have set output caching on the page, and I have set compliation debug="false" in web.config.

If I disable Javascript in my browser, the page loads very quickly, so it doesn't seem to be a general latency issue.

Any input is appreciated. Thanks.

I see some JavaScript problems on your site. Bring up the JavaScript Console in Firefox, then load your page and you will see where the JavaScript errors occur.

Thanks - I removed a reference to a .js file that I was no longer using (and that was unrelated to the tabstrip). I don't have any more Javascript errors, but the tabstrip is still loading slowly.

 

Thanks, Bruce. Do the two controls reappear quickly even when you refresh the page?


I noticed the overlap issue in Firefox as well - I'm less concerned about that than the latency since I should be able to force a table height if I need to.

 

Thanks, Bruce. I'm still puzzled. There is latency from my office computer, my home computer, and on my colleague's computer in Australia - but only when the menu controls appear in the page. Once I remove them (or even disable Javascript on the browser end), everything loads quickly. Could it be CPU issue? Could you computer just be interpreting the Javascript faster?

 

How slow are we talking about? more than 5 seconds?

Internet Explorer can sometimes run JavaScript slower, but I teste in both Firefox and IE and did not see a noticable difference in initial loading and refresh time, which is about 2-3 seconds.

Just about 5 seconds in IE.

 

Are you experiencing no delay at all? I've had a significant delay on every machine that I've tried, including the fastest one in the office - please see the e-mail below from my IT director:





Eric;


You ran the page refresh test on the following machine:


Lenovo Thinkpad T60


Intel Duo Core 2.0 Ghz CPU


1GB RAM


100GB Hard Disk - 7200RPM - more than 85GB available


The machine was just unboxed yesterday.


The network is a 100MB Ethernet, running on a 3Com Super Stack Series 3300 switch.


The Router is a Cisco series 2610,, connected via full T-1.


Given the specifications above, and the fact that other web page refreshes are running at under 3 seconds, it's unlikely the bottleneck is within our network.

Hi, Bruce --

Thanks for looking at this again. I'm happy to know that the page is loading fast for you.

The component vendor provided some client-side Javascripts that are designed to save some server processing time. They have helped a little bit on initial page load, and the refreshes are much faster. I think I can live with this.

Best,
Eric
