mtklein 7e225bdb1f nanobench: lazily decode bitmaps in .skps. ... This cuts down on tool overhead when running something like recording only, $ out/Release/nanobench --match skp --config nonrendering which doesn't usually ever need to decode the images. The actual measurements for recording don't change, as the decode is not in the timed section. It just skips irrelevant code, removing it from the profile and making the tool run faster. This does, however, make a significant difference for playback speed. Most skps draw faster with this patch, some slower. I don't really have a good intuition for what's going on here. There is a fixed clip acting as a viewport, so there are probably lots of images that don't ever need to be decoded. Ideas? Is this perhaps because we're now blitting from smaller, partially decoded source images? ~/skia (clean) $ compare clean.log lazy-decode-bitmaps.log tabl_slashdot.skp_1 2.76ms -> 4.33ms 1.57x tabl_slashdot.skp_1_mpd 2.79ms -> 4.07ms 1.46x tabl_sahadan.skp_1 3.41ms -> 4.87ms 1.43x tabl_googleblog.skp_1 1.52ms -> 2.05ms 1.35x tabl_techmeme.skp_1_mpd 1.14ms -> 1.51ms 1.32x tabl_transformice.skp_1 2.61ms -> 3.43ms 1.31x tabl_sahadan.skp_1_mpd 3.54ms -> 4.48ms 1.26x tabl_techmeme.skp_1 1.01ms -> 1.27ms 1.26x tabl_nytimes.skp_1_mpd 1ms -> 1.23ms 1.23x tabl_worldjournal.skp_1_mpd 1.98ms -> 2.43ms 1.23x tabl_pravda.skp_1_mpd 2.05ms -> 2.51ms 1.22x tabl_transformice.skp_1_mpd 2.75ms -> 3.19ms 1.16x tabl_nytimes.skp_1 874us -> 1.01ms 1.15x tabl_pravda.skp_1 1.83ms -> 1.99ms 1.09x tabl_worldjournal.skp_1 1.76ms -> 1.91ms 1.09x desk_wowwiki.skp_1_mpd 3.7ms -> 3.9ms 1.05x tabl_digg.skp_1 3.99ms -> 4.16ms 1.04x tabl_ukwsj.skp_1_mpd 3ms -> 3.12ms 1.04x desk_booking.skp_1 3.74ms -> 3.81ms 1.02x desk_googlespreadsheetdashed.skp_1 10.6ms -> 10.6ms 1x tabl_ukwsj.skp_1 2.88ms -> 2.89ms 1x desk_googlespreadsheetdashed.skp_1_mpd 11.8ms -> 11.8ms 1x desk_jsfiddlehumperclip.skp_1_mpd 891us -> 888us 1x desk_googlespreadsheet.skp_1 4.65ms -> 4.62ms 0.99x tabl_gspro.skp_1_mpd 1.97ms -> 1.94ms 0.99x desk_booking.skp_1_mpd 4.1ms -> 4ms 0.98x desk_carsvg.skp_1 18.2ms -> 17.7ms 0.97x desk_gmailthread.skp_1_mpd 2.81ms -> 2.73ms 0.97x desk_tigersvg.skp_1_mpd 19.5ms -> 18.9ms 0.97x desk_mapsvg.skp_1 88.4ms -> 85.6ms 0.97x tabl_cnet.skp_1_mpd 1.43ms -> 1.38ms 0.97x desk_jsfiddlebigcar.skp_1 1.26ms -> 1.22ms 0.96x desk_gws.skp_1 1.87ms -> 1.8ms 0.96x desk_linkedin.skp_1 2.07ms -> 1.98ms 0.96x tabl_deviantart.skp_1_mpd 118ms -> 113ms 0.96x tabl_cnet.skp_1 1.2ms -> 1.14ms 0.95x tabl_androidpolice.skp_1_mpd 5.95ms -> 5.63ms 0.95x desk_sfgate.skp_1 1.75ms -> 1.64ms 0.94x desk_twitter.skp_1 74ms -> 69.6ms 0.94x desk_youtube.skp_1_mpd 3.17ms -> 2.96ms 0.93x desk_gmailthread.skp_1 2.73ms -> 2.54ms 0.93x desk_silkfinance.skp_1_mpd 1.71ms -> 1.59ms 0.93x desk_jsfiddlebigcar.skp_1_mpd 1.45ms -> 1.35ms 0.93x desk_pokemonwiki.skp_1_mpd 2.72ms -> 2.51ms 0.92x desk_gws.skp_1_mpd 2.14ms -> 1.98ms 0.92x desk_googlehome.skp_1 563us -> 517us 0.92x desk_espn.skp_1 4.24ms -> 3.89ms 0.92x tabl_culturalsolutions.skp_1 12.7ms -> 11.6ms 0.91x desk_sfgate.skp_1_mpd 1.91ms -> 1.74ms 0.91x tabl_hsfi.skp_1 1.06ms -> 966us 0.91x desk_samoasvg.skp_1_mpd 10.5ms -> 9.47ms 0.91x desk_facebook.skp_1_mpd 3.8ms -> 3.43ms 0.9x desk_youtube.skp_1 3.52ms -> 3.14ms 0.89x desk_ebay.skp_1_mpd 2.95ms -> 2.62ms 0.89x desk_samoasvg.skp_1 10.9ms -> 9.66ms 0.89x desk_googlespreadsheet.skp_1_mpd 5.59ms -> 4.94ms 0.88x desk_mapsvg.skp_1_mpd 100ms -> 87.9ms 0.88x desk_espn.skp_1_mpd 4.7ms -> 4.12ms 0.88x desk_wordpress.skp_1_mpd 1.92ms -> 1.68ms 0.87x tabl_deviantart.skp_1 140ms -> 122ms 0.87x tabl_cuteoverload.skp_1_mpd 4.41ms -> 3.83ms 0.87x desk_tigersvg.skp_1 19.6ms -> 17ms 0.87x tabl_googlecalendar.skp_1 4.01ms -> 3.44ms 0.86x desk_blogger.skp_1 2.49ms -> 2.14ms 0.86x desk_chalkboard.skp_1_mpd 52.7ms -> 45ms 0.85x desk_weather.skp_1 2.88ms -> 2.46ms 0.85x desk_chalkboard.skp_1 51ms -> 43.4ms 0.85x desk_yahooanswers.skp_1 2.74ms -> 2.32ms 0.85x desk_forecastio.skp_1_mpd 1.26ms -> 1.07ms 0.85x tabl_androidpolice.skp_1 5.18ms -> 4.34ms 0.84x desk_yahooanswers.skp_1_mpd 3.44ms -> 2.85ms 0.83x tabl_cnn.skp_1_mpd 2.59ms -> 2.15ms 0.83x desk_pinterest.skp_1 2.69ms -> 2.22ms 0.83x tabl_hsfi.skp_1_mpd 1.6ms -> 1.32ms 0.82x tabl_culturalsolutions.skp_1_mpd 13.8ms -> 11.3ms 0.82x desk_twitter.skp_1_mpd 76.6ms -> 63ms 0.82x desk_ebay.skp_1 3.11ms -> 2.51ms 0.81x tabl_mlb.skp_1_mpd 3.17ms -> 2.53ms 0.8x tabl_mozilla.skp_1 2.42ms -> 1.91ms 0.79x desk_pokemonwiki.skp_1 2.84ms -> 2.22ms 0.78x desk_carsvg.skp_1_mpd 23.3ms -> 17.8ms 0.77x desk_wowwiki.skp_1 4.21ms -> 3.21ms 0.76x desk_amazon.skp_1 963us -> 728us 0.76x desk_css3gradients.skp_1 2.58ms -> 1.92ms 0.74x tabl_cuteoverload.skp_1 4.55ms -> 3.38ms 0.74x tabl_cnn.skp_1 3.13ms -> 2.29ms 0.73x tabl_googleblog.skp_1_mpd 2.32ms -> 1.7ms 0.73x desk_mobilenews.skp_1 3.65ms -> 2.61ms 0.71x desk_googleplus.skp_1 3.76ms -> 2.66ms 0.71x tabl_mozilla.skp_1_mpd 2.88ms -> 2.03ms 0.71x desk_pinterest.skp_1_mpd 3.17ms -> 2.21ms 0.7x desk_css3gradients.skp_1_mpd 2.98ms -> 2.07ms 0.69x desk_silkfinance.skp_1 2.06ms -> 1.42ms 0.69x desk_facebook.skp_1 4.5ms -> 3.07ms 0.68x desk_mobilenews.skp_1_mpd 4.05ms -> 2.73ms 0.68x desk_baidu.skp_1_mpd 2.73ms -> 1.81ms 0.66x desk_weather.skp_1_mpd 3.93ms -> 2.5ms 0.64x desk_wordpress.skp_1 2.15ms -> 1.36ms 0.63x desk_googlehome.skp_1_mpd 1.02ms -> 605us 0.59x desk_fontwipe.skp_1 722us -> 402us 0.56x desk_fontwipe.skp_1_mpd 897us -> 486us 0.54x desk_baidu.skp_1 3.02ms -> 1.6ms 0.53x desk_forecastio.skp_1 2.01ms -> 999us 0.5x desk_amazon.skp_1_mpd 1.77ms -> 860us 0.49x BUG=skia: Review URL: https://codereview.chromium.org/743613005		2014-11-25 14:34:03 -08:00
