No, it is a known problem when people have a slow download rate between their computer and our servers.
The only thing we did to improve it, is the location based download, which improves the download rate for a lot of users in Asian or American regions.
But at least two Turkish users reported this made things worse, as the download was redirected to Japan, which was a worse download rate than the Netherlands. To me it's unexpected that users in Turkey would be redirected to Japan, but so far I haven't pressed Victor to look into it as I know he is busy with other things. I can ask him to look soon or maybe I should also add an option in LFS to prevent redirect.
Yilmaz_Ali - when you are next online, can you switch on network debug (SHIFT+F8). If you get redirected to Japan when you download a mod, you will see a yellow chat message, I think it's "Redirect : JP" then we'll know if the same issue has affected you too.
