Duong updated HDDS-8154:
------------------------
Description:
Creating Mac instances and initializing dominates the cost of S3 token
validation, which is a big part of OM latencies for the S3 use case.
{code:java}
Mac mac = Mac.getInstance(HMAC_SHA256_ALGORITHM);
mac.init(signingKey); {code}

Cache Mac instances (in ThreadLocal as they're stateful) and reusing them help
avoid creating and initializing those objects from scratch. This will greatly
reduce the cost of S3 validation.
Code example:
