- mhh__ 6y ago10% is impressive. Albeit a web browser isn't quite the same situation but shaving even a percent off a program could save millions for a company like Google.
- srean 6y agoI do not doubt you, but for my own education could you elaborate a little on how Google or any othr company could save millions.
- jeffbee 6y agoIf you had a backend workload that draws 20MW and you make it 10% faster, you saved a million dollars per year in electricity alone. Math may vary depending on cost of electricity.
- tomtompl 6y agobut the executable that is built with these optimizations is running on people's computers, not as a backend on google servers.. or am I missing something?
- jeffbee 6y agoPerhaps I didn't understand the question. I thought the question was about why anyone would save a lot of money from software going "only" 10% faster. Most large datacenter operators will get unreasonably excited about even 1%. But you're probably right that Google itself will not directly benefit from making Chrome faster on macOS.
- bluGill 6y agoEvery cpu cycle costs energy, turning into heat which the ac needs to remove. One computer is nothing but across all their computers it adds up.
- setr 6y agoI can imagine scraping companies are probably putting serious workloads on headless chromium instances. But that's really the only thing I can imagine
- tyleo 6y agoInteresting to see this 10% number for a browser. I worked on AAA games and that is the number we saw as well.
