Whilst in transit, I was hit up by someone who I believe attended one of my #webperf lunch & learns. Told me they went live w/ a site but co-workers wondered why it was slow. Asked if I can look @ it quick. NP.

@ChromeDevTools and poked around. Took some screen shots, blocked some assets, looked @ film strip, then the waterfall and thought... hold on. That's a rather large img sprite.1 reply 0 retweets 2 likesShow this thread -
