Is it planned to consider another script executing engines than janino? There is script evaluator provided by groovy.lang.GroovyShell which can execute java scripts too. I have compared the time to evaluate the same java script by both engines and groovy engine executes significantly faster. Another positive side effect: support of groovy scripts. I believe using of new script evaluator will make improvements to the time of executing transactor functions written in java
UPD. How much are java transactor scripts executted longer than clojure transactor scripts?
