The entire cluster in the production environment consists of ARM machines. Many query statements have long execution times, with coprocessor time accounting for a significant portion. I suspect that the performance of ARM architecture machines is much worse than that of x86. Has the official team compared the overall performance of these two architectures?

There’s a big difference. I suggest binding the cores; the effect is very noticeable.

Processors with x86 architecture have more complex hardware and instruction sets, allowing them to perform more complex computational tasks. Processors with ARM architecture have a simpler design and lower power consumption, making them suitable for mobile devices and embedded systems.
