facebook js files

For some me unknown reason I get messages (testing products for SEO) regarding facebook and compressing files.
These 3 files are really slowing down the loading speed

I am using opencart 2031 and there are two new items /addons
1st is Onepage checkout form Dreamvention
2e is about cookies from TLSCookiesEU

Can comeone tell me how i can compres those files.

Compressing https://static.xx.fbcdn.net/rsrc.php/v3 ... PJ5prnN.js could save 359.1KiB (72% reduction).
Compressing https://connect.facebook.net/nl_NL/sdk.js could save 135.3KiB (69% reduction).
Compressing https://staticxx.facebook.com/connect/x ... version=43 could save 26.5KiB (68% reduction).

No, it slows down your page not because files are big, but because they're loaded from remote server.

yes I know they are big and that is the reason. But they are not on my server,
How can I figure out what file/addon is using these js files ? Do you know an answer

No, it is not. 500 Kb is not considered as big for like 10 years already.
