Hi Andrii,
I have shrinked the images but still the landingpage ist over 2 MB big (results). As I can see it the landingpage is loading a lot of images (like this) who are not implemented in the landingpage itself but on sub-pages like http://meerleben-baugemeinschaft.de/project/termine/ . Is this an error in my website or is https://tools.pingdom.com showing wrong results?
Best
Jörg
