          @anthony-delarosa Excellent, thank you.

          Here are my thoughts on how to set this up. I’m only posting below for my reference. I want to spin up a Cento 6.7 FOG server tomorrow and test the process out before you implement it. I also want to see if memcache will help with the process too. But I need to do a bit more research first.

          # yum install php-fpm
          # chkconfig --levels 235 php-fpm on
          
          Edit /etc/php-fpm.d/www.conf to use sockets
          
          # vi /etc/php-fpm.d/www.conf
          
          ;listen = 127.0.0.1:9000
          listen = /tmp/php5-fpm.sock
          
          listen.owner = apache
          listen.group = apache
          
          # service php-fpm start
          
          Setting up Apache and mod_fastcgi
          
          Install the RPMForge repo:
          
          # wget http://pkgs.repoforge.org/rpmforge-release/rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
          # rpm -ivh rpmforge-release-0.5.3-1.el6.rf.x86_64.rpm
          
          Add some priorities which repo to use:
          
          # yum install yum-priorities
           
          # vi /etc/yum.repos.d/epel.repo 
          ... add the line priority=10 to the [epel] section
          
          # yum install mod_fastcgi
          
          Configure mod_fastcgi
          
          If you have php enabled disable it
          
          # mv /etc/httpd/conf.d/{php.conf,php.conf.disable}
          
          # mkdir /usr/lib/cgi-bin/
          
          # vi /etc/httpd/conf.d/mod_fastcgi.conf
          
          LoadModule fastcgi_module modules/mod_fastcgi.so
           
          <IfModule mod_fastcgi.c>
          	DirectoryIndex index.php index.html index.shtml index.cgi
          	AddHandler php5-fcgi .php
          	Action php5-fcgi /php5-fcgi
          	Alias /php5-fcgi /usr/lib/cgi-bin/php5-fcgi
          	FastCgiExternalServer /usr/lib/cgi-bin/php5-fcgi -socket /tmp/php5-fpm.sock -pass-header Authorization
           
          	# For monitoring status with e.g. Munin
          	<LocationMatch "/(ping|status)">
          		SetHandler php5-fcgi-virt
          		Action php5-fcgi-virt /php5-fcgi virtual
          	</LocationMatch>
          </IfModule>
          
          # service httpd restart

            @anthony-delarosa Yes that is the right setting, default check in time is 5 minutes. But if you can hold off a day or so until we can test the php-fpm code. I want to see if it makes a difference on the default settings for FOG. In ‘theory’ it should make a dramatic difference in overall FOG performance.

              If you have time to help us test this new configuration, please let me know and I will provide instructions.

                hey @george1421 how ya doing? yeah sure I can help you guys out! can we schedule this for next week? had a backup meltdown n FOG hadn’t been backed up in a few days so Veeam is doing it’s FULL BACKUP and since our FOG server has over 2 TBs of images it’s backing that up now but should be done soon. Next week works?

                  @anthony-delarosa Ok when you are ready we can move forward. These instuctions are not destructive and can be reversed with a comment in a config file and restarting apache.

                  Here is where I’ve been documenting the config changes: https://forums.fogproject.org/topic/10717/can-php-fpm-make-fog-web-gui-fast

                  The change to my server has made a difference in web gui response time. But again I don’t have a large campus so its hard to scale how much of a change its made. The instructions I created were for centos 7, but should translate to 6.7 without issue. If you run into an issue I’m spinning up a 6.7 instance of centos just to be sure.

                  As part of your task. I would like you to track in vmware vm cpu usage to see when you turn on php-fpm if there is a change (in either direction) or no change. There are two parts I want to test one step at a time.

                  1. Enable php-fpm
                  2. Turn on memcache to store temporary session information in memory instead of the file system.

                  Your vm should have 3-4 GB of ram for this test. If you have more already then that is fine. I just want to make sure we have room to spawn up everything.

                  Please help us build the FOG community with everyone involved. It's not just about coding - way more we need people to test things, update documentation and most importantly work on uniting the community of people enjoying and working on FOG!

                    @anthony-delarosa Do you have golden images going? I’ve not ever heard of 2TB of images before! Then again, I don’t think anybody has had as big of a FOG environment as you. : )

                      @themcv glad to know we are the first then 😄 we use FOG for all our images and since I work for a studios company with various different shows, each show kinda has their own image! the guys have their reasons so they do a raw windows 7, 8.1, 10 images for all models then a pre-sys image once they have all the applications installed and then a production image so times 3x images per OS per model! yeah that adds up quickly lol

                        @anthony-delarosa Wow, that is a lot. Consider me in awe of your installation. : )

                        So is each image different software or is it more for each model?

                          @THEMCV both different in software and different model plus different OS so yeah it adds up! Mind you we’re a company with over 700 fx/animators/lighters/compositors etc…

                            @anthony-delarosa That’s nuts. Glad to see it in such a large deployment. Have you thought about doing golden images and just having varied images for software deployments?

                              This is off topic I know, but you should really have them use regular images instead of raw - there’s several options - ones that resize, ones that do not, lots of compression options. It’s light-speeds faster than raw, I really do mean light-speeds faster.

                                @wayne-workman I just noticed that too. @anthony-delarosa I agree, unless there’s a specific reason that you have, I would look into not doing raw.

                                    @anthony-delarosa Yes I’m available. Make sure you have a good baseline of usage. Your vmware trending is good enough. If the process works correctly you should not see all of those httpd instances in top since it should spawn php-fpm instances.

                                    Is your check in time still set to FOG defaults?
