What used to look like this:
desk_pokemonwiki.skp 9.38ms -> 9.76ms 1x
tabl_pravda.skp 237us -> 241us 1x
desk_css3gradients.skp 249us -> 254us 1x
....
desk_fontwipe.skp 39.6us -> 38.7us 0.98x
tabl_digg.skp 922us -> 893us 0.97x
tabl_gmail.skp 20.7us -> 20us 0.96x

tabl_pravda.skp 237us -> 241us 1.02x
desk_css3gradients.skp 249us -> 254us 1.02x
