Hi, Looks like the system is being slowed down for some reason. Many Ignite operations are taking a long time(>30 sec) where they should complete much quicker.
Are you able to go back to 2.7.6 on the exact same config/setup, run the system for a period of time then go to 2.8.1 and reproduce these issues? Are you using persistent store? If so, can you clean it and retry? Try disabling persistence to see if that helps, and if it does then we need to diagnose why it is causing these issues. Describe your topology? How many clients/servers/thin clients etc. Can you simplify your topology to one server (and possibly one client) and retry to see where the bottleneck is? Also try lessening the load on the system to the minimum possible to see whether these problems are throughput/load dependent. If you are unable to resolve this, but it is reproducible then describe steps/include a small reproducer and logs(including GC logs) from all nodes. https://apacheignite.readme.io/docs/jvm-and-system-tuning#detailed-garbage-collection-stats Thanks, Alex -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
