You can try setting byte-compile--use-old-handlers to nil now to see if it fixes your performance problems.
Indeed, I see the same peformance improvement you wrote about: 0.60s in byte-compiled dynamic binding mode, and now 0.48s in byte-compiled lexical binding mode. Thanks!
Not sure if I should close this issue now or at least wait until byte-compile--use-old-handlers is nil by default.
