Request response delay is too long

[SSuperMengNan]

I have deployed the application in my cluster, however I have noticed that the response time for search and booking requests is too slow, reaching around 7 seconds. Despite monitoring the CPU and memory utilization of all services, they do not seem to be the cause of the issue. Could anyone kindly provide some guidance on how I could resolve this issue?

Thank you in advance for your help.

High latency comes from long call chain, query and reservation are core functions, which involve a lot of services.
Maybe you can try to allocate more resources for all services and reduce the data size to reduce latency.
