Have anybody seen any perf improvements due to JDK8+ bytecode compatibility which this release brings ?

[Alex Miller]

I wouldn’t expect any. Would be interested to hear any perf differences you see either way though.

I don’t have any hard evidence about performance but when we first updated to the 1.10 build that generated the new bytecode, it _felt_ faster – our test suite seemed to run faster locally (so maybe the compiler got faster?). We have not seen any measurable difference in production (but we’ve had a lot of other changing going to production lately that have changed the performance dynamic of three of our servers, so any performance boost from 1.10 and the 8+ bytecode would likely have been swamped by other changes).

Likely the biggest performance gain is that compatibility fixes allow you to run up to Java 11, thus reaping any benefits from newer JVMs.

[Ghadi Shayban]

Verification time should go down with JDK8 level bytecode, which improves cold startup of clojure.jar by about 5%. (This benefit is negated by the module system in 9+ though.)
