Chrome gobbles much more RAM due to Google’s ‚Site Isolation’ protection for Spectre CPU flaws
The critical Meltdown and Spectre bugs baked deep into modern computer processors will have ramifications on the entire industry for years to come, and Chrome just became collateral damage. Google 67 enabled “Site Isolation” Spectre protection for most users, and the browser now uses 10 to 13 percent more RAM due to how the fix behaves.
“Site Isolation does cause Chrome to create more renderer processes, which comes with performance tradeoffs,” Google’s Charlie Reis says. “On the plus side, each renderer process is smaller, shorter-lived, and has less contention internally, but there is about a 10-13% total memory overhead in real workloads due to the larger number of processes. Our team continues to work hard to optimize this behavior to keep Chrome both fast and secure.”
