Constant Timer: Each thread pauses for the same amount of time between requests.
Gaussian Random Timer: Each thread request for a random amount of time, with
most of the time intervals occurring near a particular value.
Uniform Random Timer: Each thread request for a random amount of time, with each
time interval having the same probability of occurring.
Constant Throughput Timer: This timer introduces variable pauses, calculated to
keep the total throughput (in terms of samples per minute) as close as possible to a
give figure.
Synchronizing Timer: The purpose of the SyncTimer is to block threads until X
number of threads have been blocked, and then they are all released at once.

SSD.
• MySQL database supports more users for higher RAM.
• Hence SSD servers (e.g. Power Edge Series-DELL) can
boost up the performance of Moodle.
