Summary: Debugging slows down JavaScript execution 20x times Key: NETBEANS-1593 URL: https://issues.apache.org/jira/browse/NETBEANS-1593 Project: NetBeans Issue Type: Bug Components: debugger - Java Reporter: Jaroslav Tulach While working on [PR-4|https://github.com/graalvm/graal-js-jdk11-maven-demo/pull/4] I realized that Truffle debugger support in NetBeans slows down execution 20x times. Without debugger the benchmark can execute in 150ms. With debugger it takes more than 3s. At current state the great Truffle debugging feature is not suitable for a demo. To reproduce, you need: * NetBeans 10 VC2 * JDK11 * [graal-js-jdk11-maven-demo|https://github.com/graalvm/graal-js-jdk11-maven-demo] at revision 2f851ca6d922 Then you can debug the {{AppTest}} unit test and put a breakpoint to calls to {{eval}}, etc. Once the breakpoint is hit, remove it and continue. The rest of the execution will be slow - e.g. take more than 3s for each round. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@netbeans.apache.org For additional commands, e-mail: commits-h...@netbeans.apache.org For further information about the NetBeans mailing lists, visit: https://cwiki.apache.org/confluence/display/NETBEANS/Mailing+lists
