As there was no feedback about later performance issues, I close this. > Performance bottleneck (from profiling) > --------------------------------------- > > Key: FREEMARKER-80 > URL: https://issues.apache.org/jira/browse/FREEMARKER-80 > Project: Apache Freemarker > Issue Type: Bug > Components: engine > Affects Versions: 2.3.26-incubating > Environment: Linux, Java 8 > Reporter: Shevek > Priority: Major > > Major performance bottleneck running on a 32-core system, limits effective number of threads to about 6: PropertyDescriptor.getReadMethod() is synchronized, and blocks other threads. Partial stack follows: > java.beans.PropertyDescriptor.getReadMethod() > BeanModel.invokeThroughDescriptor() > BeanModel.get() > Dot._eval() > I suspect there's a workaround with using a method call directly in the FTL template, but I haven't figured it out yet. However, this is killing our performance. With Velocity, at the cost of a slower renderer, we can run all 32 cores, and get the job done faster. > I'm not entirely sure how to figure out which piece of FTL is causing this stack. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
