I am using w3 total cache plugin for my website, after activating plugin my website speed is much faster at my end . But when I check my website speed in tools.pingdom.com it is giving bad speed.So,do tools.pingdom.com gives speed results with caching or without caching?

page speed tools such as tools.pingdom.com, Yslow, gtmetrix…etc don’t just look at actual page speed (how fast your page loads) but are giving you a grade based on a specific set of rules and whether you are following those rules.

I have had websites that loaded very fast but got “not so great” scores only because I did’t meet certain criteria. I have also had sites that I felt took forever to load but got a 96% score because I went to the extra trouble to implement the list of requirements.

Long story short…it is taking your cache into account but your low score is probably based on other factors. Look at the graphs below the score and see where you can improve things.
