We are using one of the Moodle vendors recommended on Moodle site. Suddenly, after using Moodle for 5 months with a pretty normal speed, about 2 weeks ago, the system became extremely slow and everybody registered on the site is complaining.
Our people evaluating the system are not happy at all about the speed. All people accessing the site, no matter where they are in the world, insist that they cannot use the system and are asking for us not to use Moodle anymore.
The vendor says that everything is normal in his site, but he is suggesting for us to get a dedicated server for a much higher fee, of course. Is this a typical situation with other vendors of Moodle?
If sharing a server with other people using the vendor services affects the speed of the service, should the vendor have told us about this from the begining?
Any kind of suggestions will be very appreciated.
