thank you for the incite. I didn't see a speed increase on a search just now, but hopefully this helps the problem with multiple searches at the same time.

Another question: Any ideas why mysql.sock always starts up in a temp location?

The MySQL server

[mysqld]
port = 3306
socket = /tmp/mysql.sock

Any ideas why mysql.sock always starts up in a temp location?

Because that's what you've configured it to use... (it is also the default location for many installations)

jeffmic:

The MySQL server

[mysqld]
port = 3306
socket = /tmp/mysql.sock

If you wish to use a different location you'll need to set something like:
socket = /var/run/mysqld/mysql.sock

Keep in mind that you'll also need to change your client settings so they use the same location.

This mysql clogging is never ending. 2 or 3 people are searching at this time each time one search is started, and then another is added, BOTH searches suffer and become clogged. Thank you to everyone's suggestions, but none have helped solve this problem. WHY is it when multiple clients hit my search, does it clog up like this? You'll see one clog below over 200 seconds! UGH. It's so frustrating. If anyone has the ability to repair this issue, I will gladly hire them.

I only use my sidebox search to look up Product ID, Product Title and metadata keywords. EVERYTHING else can be removed from the advanced search file.

Hi Jeff,

Did you get a chance to run one of your slow queries thru phpmyadmin with profiling.

"May 6, 2008 - Not, this is not regression. But further investigation showed this seems to be only Windows and Mac issue. " ????

http://bugs.mysql.com/bug.php?id=36448

http://serverfault.com/questions/64494/concurrent-mysql-requests-are-really-slow-on-os-x

profiling seems to be fine on any of the searches I did:

Starting 24 µs
Waiting For Query Cache Lock 3 µs
Checking Query Cache For Query 12 µs
Checking Privileges On Cached 3 µs
Checking Permissions 10 µs
Checking Permissions 2 µs

Does anyone recommend that I change my storage engine to Myisam to InnoDB? There is a contribution on Zencart by Data-Diggers, but it doesn't appear in the tools menu on Zencart 1.5.1. It is approved and DOES appear on 1.3.9 though, but I'm scared to press the change button.

When working and digging into this with Dr. Byte today, we seemed to have found a solution.

1 - We changed 3 tables to InnoDB (and anything with FullText had to be changed to Normal)
2 - A few changes were made to the keys and indexes, but they actually did little in those tables.

I have 2 - 1.5.1 websites that contain the same data in the databases.
So, after changing over 1 of them with Dr Byte and leaving the other as is for now, here's the search results on TWO CONCURRENT SEARCHES using different ip address.

Site 1 unchanged: 12.9 seconds after clogging mysql and then a white screen for a bit
Parse Time: 12.983 - Number of Queries: 184 - Query Time: 12.871974807755

Site 2 with changes: 2.4 seconds, immediate screen drawing of data with no clogging of mysql

So happy today - still testing and making adjustments as needed.

The 3 tables that I needed changed to InnoDB were:

meta_tags_products_description (as I use keywords for my song artist in the side box advanced search)
products
products_description

I filtered out manufacturers and categories in my header.php.php file for advanced-search so those tables didn't need to be changed to InnoDB at this time.

I'll update as I find out more. WHEW!!

Good to know Jeff , thx for sharing that .
