We had an alert on enwiki for First Visual Change on mobil. Checking WebPageTest the increase is there:
And no change on TTFB (at least it doesn't look like it):
Need to check when new Chrome was rolled out and if I can see something in WebPageReplay (we haven't updated Chrome there yet).
No change in WebPageReplay and I could see that it happened in the same time of Chrome 75 for WebPageTest. On Wednesday I'll roll out 75 for WebPageReplay and I can create an upstream task if we get it there too.
Yep got a small change on Browsertime/WebPageReplay too (one tick):
However Chrome 75 gives more stable values than before on enwiki:
Let us see when 75 rolls out for real users.
Looking at June 16 - now. Shape of the ramp-up during that period:
loadEventEnd:
| browser_family | browser_major | median | p90 | p95 | count |
| Chrome Mobile | 74 | 1277.0 | 3703.0 | 5851.0 | 1274072 |
| Chrome Mobile | 75 | 1166.0 | 3259.0 | 4911.0 | 1345331 |
| Chrome | 74 | 1422.0 | 4649.0 | 7221.0 | 1148045 |
| Chrome | 75 | 1388.0 | 4527.0 | 6951.0 | 1011191 |
firstPaint:
| browser_family | browser_major | median | p90 | p95 | count |
| Chrome Mobile | 74 | 883 | 2347 | 3433 | 1272779 |
| Chrome Mobile | 75 | 800 | 2060 | 2968 | 1344102 |
| Chrome | 74 | 1117 | 3514 | 5251 | 1145951 |
| Chrome | 75 | 1071 | 3393 | 4983 | 1009683 |
Chrome 75 looks like a significant performance improvement in RUM across the board!
8.7% faster median loadEventEnd on mobile and 2.4% faster on desktop.
9.4% faster median firstPaint on mobile and 4.2% faster on desktop.
