I am getting very slow performance on most isochrone requests. With a time limit of 30 minutes, the response time is extremely slow (~5 sec). Is this a known issue? Is there something I can do speed things up? I’ve already tried tuning the JVM/OS with open file limits, limit swappiness and gave 24GB heap to the java process. Even with CH, the requests are slow.
