Loading Speed of site
I am having one of my developers rebuild a site for a client (conversion of HTML to C5) the problem I am finding is that the site is incredibly slow. The pages load slowly and it seems to be getting worse over time.
I am afraid that the client may force me to use another CMS, which would be a real drag as we have almost completed the site and I spent time telling the client just how great C5 was.
I am not sure if this is a C5 issue or if anyone else has experienced these types of issues.
Here is the -http://vtabarbados.com/c5
If anyone knows how to fix this or has any suggestions, please let me know.
You could look at this thread:
and talk with Phallanx about permission to use the tweak he created.
I saw some improvements after enabling compression using the tweaks on this this site too:
From Page speed I see the following:
Combine external CSS
Leverage browser caching
Specify a Vary: Accept-Encoding header
Specify image dimensions
Use efficient CSS selectors
Hope that helps.
It's not Concrete5, although all the stuff that goes in the background can hinder.
Your images are not that heavy, but on my broadband they still flow slowly?
You need to check again and as myTooq says page speed is NOT happy.
Something is amiss?
Try looking at FF results.
Hope this helps.
Brian and Steev, thanks for taking the time look over the site and make suggestions about what the issue may be.
I have been forwarding your comments to my developer. The original developer that I had working on this site had a number of problems, I have a new developer who is helping fix a number of issues and I have asked him to look into the issue with page load speed.
I am wondering if the original setup of the site and installation of C5 was done in error.
Would either of you guys suggest a re-install?
A clean install wouldn't hurt. Just back up database and make copies of everything if you need to.
I'd follow up with the page speed recommendations first and see if you can get it into the 90-95/100 range. If it's not there, then a tear down might be in order.
You ready for this?
Your installation came with sample content hence the reference to the slideshow which you are not using. I asked the community about the reason for it. never had an answer. So fresh install WITHOUT sample content will rid you of unnecessary code, calls and errors.
Page Speed Score: 76/100
Enable compression and Leverage browser caching
Try this code in your .htaccess file:-
Header append Vary User-Agent env=!dont-vary
Header set Cache-Control "public"
Header set Expires "Mon, 15 Oct 2011 20:00:00 GMT"
Specify image dimensions - good to do.

Use efficient CSS selectors
Should be done, but a bit of work. Most people wouldn't bother. (superfish issue)

There is more but it's a start.
I make sure all my sites hit 90+, although couple need kicking!
As I mentioned, I'm no expert, so thanks for this. I'm sure this will help James, but I'm guessing I can fix a couple of things on some of my sites too.
Thanks for the info and taking time to post this.
Wow I did not realize that the site was setup with sample content - Yikes!
My developer is working on it, I have also contacted my hosting company to have them review my configuration to see if there is anything that can be done from that end.
Once again Steev thanks for your detailed information, it is majorly appreciated.
