Looking at the bottleneck
The tasks performed by proxy tools are relatively straightforward and, typically, this type of tool is extremely performant. However, like any software, resources are not infinite.
Sometimes, we see some slowness in microservices that are behind a proxy, and we think the problem is in the microservice. Therefore, we try to improve performance by increasing the number of instances for a microservice that is behind a proxy. This type of behavior seems logical, but it is worth remembering that the load of all microservices is on the proxy, which may be the bottleneck for the microservices.
It is very important to verify that the machine resources, where the proxy tool is installed, are sufficient for the expected load. ...
