I've run into a situation where there is poor Moodle performance, especially when a group of students take an exam.
What I need now is general advice on the following:
- Currently running Apache. It was suggested that nginx might be a bit faster. Any comments on that?
- Currently using DSO as the PHP processor. It was suggested that fastCGI might be better. Any comments on that?
- Is it better to work at tuning what we have (Apache/DSO) or to first move to one or both of the options above. Where would you begin?
