[1] - This covers troubleshooting of performance issues within GemFire itself only, driven by GemFire configuration, product bottlenecks. It does not include issues within an application, library, or other Java code being run by the JVM or issues due to other processes running in the environment.
[2] - Bug fixes are prioritized by GemFire Engineering with input from Tanzu Support and our customers. There is no guarantee of an immediate fix and the Tanzu GemFire Support retains the right to close out support tickets if a fix is not immediate. Tickets will not remain open waiting for R&D to discover root cause, fix, test, or deliver new product.
[3] - GemFire Support will provide limited support for tuning JVM settings such as diagnosing issues with memory, cpus, heap, or GC. Tuning can help in some situations, but it is not a panacea and is not an appropriate solution for every situation. Often it is a bigger and more extensive issue that will be out of scope and require an engagement beyond the Support team.
[4] - GemFire Support is often asked to triage environments related to observed performance issues or changes in behavior. A quick triage to assess health is offered, to assess whether the GemFire product configuration is driving any piece of the issues. GemFire support does not tune heap or GCs, but can provide their observations for consideration. Beyond this, performance is completely out of scope for GemFire Support.
