Making My Website Faster


I have used the free version of WP Smush for awhile now and I am just starting to try the trial for WP Smush Pro. Your website tells me my website is slow and recommends I compress my pictures. I have compressed all of them and I still don’t have a very good loading time. Is there anything else I can do to increase my speed? I also installed Hummingbird with my free trial but it doesn’t give me the option to configure it so I don’t know if it is actually doing anything in the background or not..
