Hello, we need help. Our eshop loads slow, here is a slow query log.

Code: Select all

# Query_time: 7.146166 Lock_time: 0.065719 Rows_sent: 20 Rows_examined: 15454
SET timestamp=1449006931;
SELECT p.product_id, (SELECT AVG(rating) AS total FROM oc_review r1 WHERE r1.product_id = p.product_id AND r1.status = '1' GROUP BY r1.product_id) AS rating, (SELECT price FROM oc_product_discount pd2 WHERE pd2.product_id = p.product_id AND pd2.customer_group_id = '1' AND pd2.quantity = '1' AND ((pd2.date_start = '0000-00-00' OR pd2.date_start < NOW()) AND (pd2.date_end = '0000-00-00' OR pd2.date_end > NOW())) ORDER BY pd2.priority ASC, pd2.price ASC LIMIT 1) AS discount, (SELECT price FROM oc_product_special ps WHERE ps.product_id = p.product_id AND ps.customer_group_id = '1' AND ((ps.date_start = '0000-00-00' OR ps.date_start < NOW()) AND (ps.date_end = '0000-00-00' OR ps.date_end > NOW())) ORDER BY ps.priority ASC, ps.price ASC LIMIT 1) AS special FROM oc_product p LEFT JOIN oc_product_description pd ON (p.product_id = pd.product_id) LEFT JOIN oc_product_to_store p2s ON (p.product_id = p2s.product_id) WHERE pd.language_id = '2' AND p.status = '1' AND ( p.mod_customer_group_restrict IS NULL OR FIND_IN_SET( 1, p.mod_customer_group_restrict )) AND p.date_available <= NOW() AND p2s.store_id = '0' GROUP BY p.product_id ORDER BY p.date_added DESC, LCASE(pd.name) DESC LIMIT 0,20;
What is issue with this? Thanks.

I will not be of much help, to just publish a rather strange looking piece of code.
containing Variables, not commonly used in a default OC, and expect assistance.

That's MySQL slow query log, not code.

Make sure you totally disable product and categorie count in your shop (look for extensions that will remove this grom opencart)

next optimze your database for faster acces and queries

I have disabled product count in categories long time ago. Database is optimized (has about 20 MB).

We need probably something for better cache. On main page we have lot of products, so there is probably issue.

You can alter your database so all tables are altered from myisam to innodb and add tables indexes this will dramitically reduce databse stress and make your site much faster

>> I have disabled product count in categories long time ago. <<
Does not help very much, it's been counting anyway, every time someone asks for, because it has to know, to make the Pagebreak System work.

Much better, CACHE those Values, then, you even can display the Numbers, without experience any performance-loss, and serve your Customers better, by telling 'em, what you have on Display in real!
!!! OC v.1.5.6.x ONLY !!!
Good Luck ;)
Ernie

Sample improved Test Site, with other Speed-Up Tips on the font Page mentioned as well, such as the link to the upmost finest Atomix TURBO change to INNODB + Full DB Indexing Tool!
http://www.hitline.info/shop/

Code: Select all

	// http://octurbo.com/caching-opencarts-category-counts/
	// $query = $this->db->query($sql);
	// return $query->row['total'];
	// http://octurbo.com/caching-opencarts-category-counts/

	$cacheid='product.gettotalproducts.'.md5($sql).(int)$customer_group_id;
	$total=$this->cache->get($cacheid);
   if ($total === null ) {
       $query = $this->db->query($sql);
       $total = $query->row['total'];
       $this->cache->set($cacheid,$total);
   }
   return $total;   
	}
	
	// END opencarts-category-counts

I think you may struggle to find this for such an old version of OC. You may want to try a commercial posting to see if any developer can assist you.

Well, there are several ways, to speed up your OC. :D
1. Use this, to cache the Category Product-Number Values. It will
dramatically improve overall Listing Page Loading:
Cache category data
Caches category data for Opencart 1.5 to make it faster.
Opencart installs with alot of categories are really slow.
https://gist.github.com/weismannweb/a16 ... 89ca1d1209
---
2. Cache your Database Stuff, it also has a remarkable effect on Loading. But
only after changing the echo $ouput; variable, obviously written
wrongly :crazy: in your OC Version system/library/response.php file , also
in the system_db_cache_pnsol.xml VqMod File too, to match the variable:

Code: Select all

FROM:
<search position="after" offset="1"><![CDATA[echo $output;]]></search>
TO:
<search position="after" offset="1"><![CDATA[echo $ouput;]]></search>
to make it work with your Version Code, if the wrongly written Variable really exists. :laugh:
DB Cache
OpenCart 1.5.6.x DB Cache module
Caches database sql queries to improve performance to 10 times.
Automatically drop affected cache entries after any modification operation: insert/update/delete
https://www.opencart.com/index.php?rout ... n_id=25388
---
3. Make sure, to use MySqli, it dramatically improved Page Load,
and check your BOTH config.php (ROOT +Admin) Driver
settings, to find out:

Code: Select all

define('DB_DRIVER', 'mysqli');
MySQLiz - MySQLi support
MySQLiz module adds MySQLi database driver support to OpenCart for old
versions of Opencart moved to modern hosting.
https://www.opencart.com/index.php?rout ... n_id=13041
---
Mysqli w/ SSL Certs
MySQLi with SSL support. This will allow for secure database communication via SSL.
This is the best way to add a layer of protection to your cart.
https://www.opencart.com/index.php?rout ... n_id=18572
---
Mysqli for Opencart 1.5.x
Add Mysqli to your older opencart versions BEFORE 1.5.6.1!
https://www.opencart.com/index.php?rout ... n_id=30233
---
4. Use the enclosed .htaccess file, just RENAME the:
RewriteBase /bright/
to match your Site Subdirectory, if you use an URL like www. yoursite/shop/
otherwise, if your Shop is located in the SITE ROOT Section, make it look like:
RewriteBase /

Code: Select all

## If your opencart installation does not run on the main web folder,
## make sure you folder it does run in ie. / becomes /cart/ or /shop/ 
## it's now set to match the SubDirectory: /shop/
RewriteBase /bright/
in Line 79 of the .htaccess File.
The .HTACCESS Zip File has now been removed again, it's available on personal request!
---
5. LINK your Styles and Scripts in the Theme header.tpl File
In your THEME header.tpl File, change the Links to Stylesheets and Scripts
to an absolute http Value instead of having them linked 'internally'. And if
your Shop runs by a http(s):// www. yourshop/ ... setting, make the Style + Script
links looking the opposite way, like http(s):// yourshop/ ..., to make all those
Styles and Scripts Cookie-Free, as this is called. :D
A sample header part, containing such ABSOLUTE URL Values, since my Sites are called by http(s)://WWW. ....

Code: Select all

<link rel="stylesheet" type="text/css" href="http://openshop.li/shop/catalog/view/theme/default/stylesheet/stylesheet.css" />
<?php foreach ($styles as $style) { ?>
<link rel="<?php echo $style['rel']; ?>" type="text/css" href="http://openshop.li/shop/<?php echo $style['href']; ?>" media="<?php echo $style['media']; ?>" />
<?php } ?>
<!--[if IE 7]> 
<link rel="stylesheet" type="text/css" href="http://openshop.li/shop/catalog/view/theme/default/stylesheet/ie7.css" />
<![endif]-->
<!--[if lt IE 7]>
<link rel="stylesheet" type="text/css" href="http://openshop.li/shop/catalog/view/theme/default/stylesheet/ie6.css" />
<link rel="stylesheet" type="text/css" href="http://openshop.li/shop/catalog/view/javascript/jquery/ui/themes/ui-lightness/jquery-ui-1.8.16.custom.css" />
<script type="text/javascript" src="http://openshop.li/shop/catalog/view/javascript/DD_belatedPNG_0.0.8a-min.js"></script>
<script type="text/javascript" src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.8.16/jquery-ui.min.js"></script>
<script type="text/javascript" src="http://openshop.li/shop/catalog/view/javascript/common.js"></script>
<?php foreach ($scripts as $script) { ?>
<script type="text/javascript" src="http://openshop.li/shop/<?php echo $script; ?>"></script>
<?php } ?>
---
6. Make your Images cookiefree, your Version is easy able to.
Change in your ROOT config.php File the URL Value, by
example, if your Shop runs under http(s):// www. Yourshop,
make the image URL like http(s):// Yourshop,

Code: Select all

define('HTTP_SERVER', 'http://www.opencart.li/bright/');
define('HTTP_IMAGE', 'http://opencart.li/bright/image/');
// HTTPS
define('HTTPS_SERVER', 'http://www.opencart.li/bright/');
define('HTTPS_IMAGE', 'http://opencart.li/bright/image/');

7. ATOMIX Turbo Database Indexer.
You already told me, to have used this fine Tool, but for others,
I mention it also, since it's a MUST, to have the DB fully indexed:
https://github.com/IP-CAM/opencart-turbo
---
All of those extensions and infos above should technically function, if you use a stock OC. 1.5.3.1, I assume.
And then, come back an tell us, what gtmetrix.com means about it. Make a Test, before you change
anything, and one after, then, you'll know in detail, and we do too ;)

Good Luck ! ;)

Thank you very much Ernie!
In the meantime, I have tried to move to another host and it is even worse situation:
502 Bad Gateway , so even GTmetrix could not work.
I will have to move to some Cloud VPS hosting in order to try to make the things faster (and to have some time to rebuild it in OC 3).
Will keep you posted.

Good for you ! My test Servers are in a shared IP Environment, among
about ~1'000 others, as I found out, but it does not keep a 3k product OC
from producing 100/92 in ~3s D/~5s M on the Vancouver GTMETRIX Site
in mobile and desktop tests on a 18pr. category Page, which is 8'300 KM away. ;)
So, just make sure, to select the TOP LEVEL Server Owner, to rent your
Server Space, but not some Sub/Sub/Sub/Hoster, only getting a small
Portion of Server Power for their Clients. On my way, I came trough
cheaper Sub-Hosters, to end up, where those in charge really are in
full charge of the Servers used. It may not always be the cheapest
solution, but for sure the best.
Good Luck! ;)
