has been annoyingly sluggish ever since. Pinging Google sites via command-line shows heavy packet losses. I use the same browsers in Linux (Chrome & Firefox), and the same browsers in Windows. Still, performance of all Google (and related) sites is very poor in Linux (but OK in case of Windows) due to an arcane reason that is still now clear to me. Even (innocuously) normal sites with Google ads take 4-5 refreshes to load properly. And don’t forget almost no site (ok, except some only-HTML stone-age sites still lurking around) in the world today are devoid of those nasty Google ads.
So until I solve the mystery, Google will keep me frustrated in Linux.
