I have been using a custom build of Moodle 1.9 on the TKL LAMP 11 build. We use it extensivly in our classroom. I recently setup the new 12.0 version of Moodle 2.3 in a vm.
I am learning my way around the new interface but it strikes me how much slower it is than 1.9. I looked around and one of the things I notice is there doesn't seem to be a php accelerator in the build. i.e. eAccelerator or APC. As a simple test I tried doing a apt install of php-apc but it killed apache.
That doesn't really suprise me as I have encountered issues with other packages and TKL in the past. I am pretty all the LAMP based TurnKey web appliances should come with a php accelerator pre-integrated. I wondered if anyone has experiance with this issue and or any sugguestions.
