> I've made a couple optimizations and merged to main. > > With the optimizations it's still about 38% slower than the non-concurrent code (including the HashMap optimization for the non-concurrent that went in). Nothing stands out in the profiler as a problem anymore; I guess that's what you get replacing HashMap with ConcurrentHashMap and more especially replacing ArrayList with ConcurrentHashMap in L0. > > I still do not know how to fix the ram usage estimates; any suggestions? I believe the issue is related to the Java Platform Module System, which was introduced in Java 9. You can modify the following section in the [gradlew script](https://github.com/apache/lucene/blob/3c163745bb07aed51b52878de0666f1405696147/gradlew#L221) to avoid the exception: https://github.com/apache/lucene/blob/3c163745bb07aed51b52878de0666f1405696147/gradlew#L221 **modified version** ```shell JVM_ARGS=" -Ptests.jvmargs=\"--add-opens java.base/java.lang=ALL-UNNAMED --add-opens java.base/java.util.concurrent.atomic=ALL-UNNAMED\"" # Collect all arguments for the java command, following the shell quoting and substitution rules eval set -- $JAVA_OPTS $GRADLE_OPTS "\"-Dorg.gradle.appname=$APP_BASE_NAME\"" -classpath "\"$CLASSPATH\"" org.gradle.wrapper.GradleWrapperMain "$APP_ARGS" "$JVM_ARGS" ``` After making this change, the exception should no longer be thrown. However, the test may still fail due to an AssertionError, as shown below: ``` java.lang.AssertionError: expected:<1185336.0> but was:<486483.0> > at __randomizedtesting.SeedInfo.seed([A41F62241729FCF:CF0592627AF94878]:0) > at org.junit.Assert.fail(Assert.java:89) > at org.junit.Assert.failNotEquals(Assert.java:835) > at org.junit.Assert.assertEquals(Assert.java:555) > at org.junit.Assert.assertEquals(Assert.java:685) > at org.apache.lucene.util.hnsw.HnswGraphTestCase.testRamUsageEstimate(HnswGraphTestCase.java:789) > at org.apache.lucene.util.hnsw.TestHnswFloatVectorGraph.testRamUsageEstimate(TestHnswFloatVectorGraph.java:37) > at java.base/jdk.internal.reflect.NativeMethodAccessorImpl.invoke0(Native Method) > at java.base/jdk.internal.reflect.NativeMethodAccesso ``` -- This is an automated message from the Apache Git Service.
