I wonder if you have in Europe servers to see if this kind of MSS or MTU is the same as in your American servers because mine should look like this one below ;

My real MTU is 1496 not 1436 and I don't know if your site actually doesn't show my real MTU and real MSS ! this is not fair !
Sometimes is 1456 but most of the time from couple days ago looks to have 1436 as MTU ! what the heck ?!
My real DLD is 1,7 MB/s even from America sites!
This one is from my local !
