Please elaborate the best methodologies and strategies to achieve a lesser load time in both server side and Magneto side. Tried out various strategies but couldn't achieve a load time of less than 4 seconds consistently. In some cases if I achieve 3.2 seconds or more it is not consistent. Please suggest the techniques you have employed to achieve lesser load time.
Has anyone integrated Google Page Speed Module either in Nginx or Apache? Does it improve the page load time?
