Thanks a lot for sharing your experience ! Actually some people have told me that there can be complications if you want to cover it up later . I ' m not particularly set on it being an arm band , so the quarter sleeve idea might be a good one . <| sep |> Without videofile could be served directly from diskpage cache using sendfile . With it should be copied into userspace program , ciphered and copied into socket buffers . Without our vidro servers easely sent 10 Gbitsec and there were free cpu . Now they stuck at 8 Gbitsec and most cpu is in kernel , not userspace . So , encryption is not slow by itself . But it forces to use slower methods to make its usage possible . <| sep |> What does dial mean ? <| sep |> All these guys sitting in their Mom ' s basements clearly know way more about it than you do . selfawareness . exe has stopped working
