Latency sensitive applications may notice an increased latency due to a request to the external plugin upon every authenticated request to MinIO. User are advised to provision their infrastructure such that latency and performance is acceptable.

A primary responsibility for any HTTP client is to efficiently manage network connections. Creating and establishing new connections require a fair amount of overhead and added latency. OkHttp will make every effort to reuse existing connections to avoid this overhead and added latency.
