Recommended Posts

Our site www.landroversalvage.ca if you select the OEM new Parts from the middle of the screen it takes 25 seconds to show the folder group then same for each part - im getting BS from my web hosting they say they have tested it and it works fine on there servers and say i might be running an old version of OS Commerce (how do i check this?) but my customers are growing weary of the delays - can anyone tell me whats wrong here? cheers Dom

It would work faster if you didn't run the whole thing in SSL mode.

 

The only thing you need SSL for is "sensitive information exchange".

 

It shouldn't be used for your catalog.... IMHO...

:blink:

If I suggest you edit any file(s) make a backup first - I'm not perfect and neither are you.

It is most likely from an incredible amount of queries. A good read (but a long one) is this thread: A Store Speed Optimization in Progress, Step by step from a vanilla install!.

 

To cut the story short I think you would be helped most by the contribution Optimize categories box, Optimize tep_get_tax_rate() method and for the admin this one also helps: tep_get_category_tree optimization.

 

And germ is right, the whole catalog in SSL does not help either.

I really appreciate this guys - i didnt install OS commerce a friend did then left me with it, so i have a programmer that does the easy populate for me, with what you suggested is this something that i can do myself or should i goto an expert?

 

I am so grateful that you answered so quick i have been pulling my hair out as to why lol

My personal opinion is that the contributions I suggested are not difficult to install, but you seem to suggest you know nothing about PHP. Messing with a live store and not knowing what you are doing is always tricky.

 

Best thing to do would to have a backup of your shop locally, do the changes, confirm everything works and upload the modified files (always have a backup ready). But I guess you don't have that either?

 

Better ask your programmer then.

SSL is good for the checkout part to. If you have a creditcard option in the shop for example. SSL should not slow down the shop that much...

I've just visited your site and looked around. I found it extremely slow, particularly in the shopping cart, but also your main site pages although they're nowhere near as slow as the shopping cart.

 

I'm in Canada too, so I wouldn't expect it to be so slow since you appear to be using Bell Canada web hosting.

 

They can tell you whatever they like, but I think there's definitely a problem with your hosting. However, the biggest problem for the shopping cart seems to be the fact that it's being delivered using SSL - and a shared SSL at that. If the webhost has hundreds of websites all using the same shared SSL, that could explain the very slow response times.

 

On a typical installation, where the osCommerce is installed in a folder, I would say the SSL problem would be easy to fix (see #6 in this post), but since your cart uses only the SSL URLs it's harder to say where and how to fix the problem (instead of http://www.landroversalvage.ca/cart you site uses https://secure9.securewebexchange.com/landroversalvage.ca/).

 

If you want to PM me I might be able to help you more, but at this point everything seems to indicate that your server and your osCommerce configuration are the problem.

 

Regards,

Jade

MY shop has been very slow too. Enable Gzip Compression, it speeds up the whole shop significantly and makes it a lot faster. You find Gzip Compression here: go to admin, configuration and select GZip Compression. Switch to "true". It works perfect with my shop (though it is heavily modified with STS etc). GZip is an osc standard, no installation hassle. I wish I would have known this earlier. GZip compresses the files which are send to the browser, the browser decompresses and renders it as normal (however if the browser does not support GZip, the files will be send uncompressed). This saves you bandwidth also. Your server should support zlib with PHP and your PHP version should be greater than 4.0.4. This should not be the problem, as I am writing this in October 2010.

Check the image sizes. By default OSC does not resize the thumbs you have to upload already edited thumbs or you will have 1.5MB thumbnails like the Land Rover guy does

 

http://www.landroversalvage.ca/store/images/classic.jpg

 

 

that is a 1.5MB image displayed as 150x150 thumb, do that for most of your images and the site slows to a crawl as more and more images get uploaded.

 

enabling compression helps but address the root of the issue... that is if your issue is the same as his.

I have just taken a quick look at your site, and it appears to load slowly. I sugggest this is down to your image sizes as already mentions. You need to add an add on that will automatically produce thumbnails. There are many there, so pick one.

REMEMBER BACKUP, BACKUP AND BACKUP
