Limitations
The VNC protocol is pixel based. Although this leads to great flexibility (e.g., any type of desktop can be displayed), it is often less efficient than solutions that have a better understanding of the underlying graphic layout, like X11. Those protocols send graphic primitives or high-level commands in a simpler form (e.g., open window), whereas RFB just sends the raw pixel data.

Famous quotes containing the word limitations:
“The motion picture made in Hollywood, if it is to create art at all, must do so within such strangling limitations of subject and treatment that it is a blind wonder it ever achieves any distinction beyond the purely mechanical slickness of a glass and chromium bathroom.”
—Raymond Chandler (1888–1959)
“... art transcends its limitations only by staying within them.”
—Flannery O’Connor (1925–1964)
“No man could bring himself to reveal his true character, and, above all, his true limitations as a citizen and a Christian, his true meannesses, his true imbecilities, to his friends, or even to his wife. Honest autobiography is therefore a contradiction in terms: the moment a man considers himself, even in petto, he tries to gild and fresco himself.”
—H.L. (Henry Lewis)
