when I try to load makerlab-electronics.com it takes time to load 

then if I try to add www.makerlab-electronics.com the loading time is more faster.

Hey @niceeee.
 
Thanks for reaching out. 
 
I appreciate that you have provided your online store URL as that is very helpful! Just to gather some additional context, are you still experiencing slow loading times to your online store? 
 
The reason that I am asking is because I navigated to your online store using both URLs mentioned, I was able to successfully loaded the homepage within one or two seconds - which is ideal for your visitors. With that being said, we do have an awesome article that goes into the changes that you can make to increase your online store speed: Improving your store speed.
 
Looking forward to your response.
