Website loading is soooooo slow

[electrostuff_de]

I need your help because I can not identify the error. The problem is that our shop loads very slowly. When I clicked on an article and clicked on the shop's logo to reload the homepage, the whole website is downloaded again. It seems to me almost as if the problem with the htaccess file has to do, therefore times the code here:

Any ideas? Thank you for your help!

Before modifying your .htaccess file, the slow performance of your shop can be due to a number of reasons that aren't related to your .htaccess.

 

First, check your caching. Go under "Advanced Parameters" and "Performance". Clear your cache, then enable your Smarty Cache, and enable memcache below.

Reload your store and click around and your site should be considerably faster.

 

Then check if you can enable CCC caches. Enable one at a time to make sure your site is loading properly, as some themes may be rendered incompatible. 

Your site should be considerably faster once that is completed.

 

If you are still experiencing slow performance, it could maybe be a module that is slowing your site down. Go in the config file, store_root/config/defines.inc.php and set line 42 or debug profiling to true:

define('_PS_DEBUG_PROFILING_', true);

Reload your site and scroll to the bottom of your site and you should see exactly what is loading, and the latency of each module and SQL query in milliseconds. It might be a resource hungry module slowing down your site.

 

The last thing I could think of  is your hosting. Shared hosting packages tend to be slower since they share resources with other users.

 

If you still don't see any speed increases, maybe other forum users have better suggestions. But these are all the methods that I use on stores I work on.

Thank you for your suggestions.

 

I've figured out that the oviclayoutcontrol is slowing down our shop, but it's the theme... sadly the developer of this theme does not give some support. I'll have a look at the code, maybe I can do something.

can you provide your shops url?  you can delete it later...
