Magento

ok I have no idea what I did or what magic element I tweaked (I think it was the prefork.. my original settings were mental) but my results on magebenchmark has shot from 5 TPS to 40 TPS?? go figure.. well at least this is more in line with what I think it should be and I am less embarased by the results

Let just hope that what ever tweaking I did I have not undone since the last benchmark.. will leave things to settle down and hope for the best.

Thanks again for all the tips

Gr8 thread to follow. I was looking for best option to “save session data in” and landed in this thread. Very helpful

Interesting thread thank you

Can anybody provide some help with the temporary cache (tmpfs).

I followed the steps but now I get an error, which doesn\’t really tell me anything
http://www.moress-charms.com/order/

how do I undo this?

how do I get this to work? instead of /var/www/html/magento/var/cache I used my path which is /home/username/www/order/var/cache

Thanks in advance!

Using Centos 5.4? You are going to need php 5.2 so this is what helped me:

and then add this:

Next, install php like this:

And now - installing memcached:

I had to install pecl-memcached not using yum because there is a version conflict:

Configure as you have seen things configured in the beginning of this thread, install magento, add this into your local.xml (before the closing </global> directive):

- do your restarts - etc. and you should have a working memcached/magento installation.  I saw big improvements in responsiveness - even having mysql with query cache and memcached running on the same server.

In case you need it:

insert:

and restart mysql:

Here’s a simple tutorial on how to improve Magento’s performances without changing core files.
I’m sorry this tutorial won’t help users hosting their store on a shared environment.

Installation instructions will continue my fedora / centos install guide

5 - Use a tmpfs filesystem for magento/var/cache
Supposing your magento leaves in /var/www/html/magento, we need to :
Stop apache

service httpd stop

Clean cache

cd /var/www/html/magento/var/cache/
rm -rf mage*

Mount a tmps cache

mount tmpfs /var/www/html/magento/var/cache -t tmpfs -o size=64m

For more space change 64m by any value (take care of your system RAM)

Restart apache

service httpd restart

This sets up tmpfs as a one time test environment that doesn’t survive reboot. In order to allow it to come back automatically on reboot, after doing the above, you need to add a line to your /etc/fstab file as follows

Code blocks are never to be trusted on this board, it insists on splitting /var/www/html/magento/var/cache/ with a newline

In the above, uid is your login id and gid is your group id your apache process is running under. If uid and gid aren’t set, they default to root, and the first person accessing Magento upon reboot gets the error screen with a report id to hunt for and the stack trace telling you the cache directory is not writeable.

Its a bit late but to ‘undo’ simply un-mount with

umount /var/www/html/magento/var/cache

Good to see the tutorial on how to improve Magento’s performances without changing core files. I am sharing this with my mates too. Very helpful for me as well.
