In the performance documentation it says:
On a Unix/Linux system, performance can be greatly improved by allowing the webserver to use the system zip/unzip commands (rather than PHP-based zip libraries) - visit Admin/Configure/Variables and enter the path to the relevant executables. (Similarly, filling in the path to du will improve Moodle's speed at listing directory contents.)
I would like to follow this up but, despite extensive searching around in various places for more info, I am still stuck! As I understand it, the 'system zip/unzip commands' use the same utility as when I unzipped Moodle on the web server - am I correct? But I have no idea of the path to it - could anyone give me any idea re where I should start looking and what the file I am looking for might be called? As for 'du' - does this mean 'disk usage'? Again, I would be really grateful for any hints on how to get started with this. (Our web server is a managed server.)
Many thanks for any assistance,
Jenny
