Re: [ANN] 1.10.0-beta4
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.)

Re: [ANN] 1.10.0-beta4
Likely the biggest performance gain is that compatibility fixes allow you to run up to Java 11, thus reaping any benefits from newer JVMs. On Friday, October 26, 2018 at 11:09:39 AM UTC-5, Sean Corfield wrote: > > 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?).

RE: [ANN] 1.10.0-beta4
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).
