What tools can test the concurrency, TPS, QPS, etc. that dgraph can bear on my server

I want to test the performance of dgraph. Can JMeter test dgraph?

You’d first have to explain what “performance” is. There are many many facets to “performance”, with many intermediary factors.

Internally, the dgraph repository is home to many benchmarks. Externally, you can check out this repository (- h/t @rajas) which benchmarks Dgraph.

Be aware that you need to make your environment as immutable as possible to perform meaningful benchmarks. Most people are actually unable to attain useful benchmark results due to the lack of isolation of environments.
