https://paste.ubuntu.com/p/zKYc6rk6WY/ Benchmark with AclAuthorizer::updateCache With aclCount=50 and resourceCount=200000, 200000 call to updateCache took ~59 seconds The cpu overhead is mainly on re-hashing (everytime when the resourceCache hits 75% of the capacity). But we can overlook it. The memory overhead is M = (aclCount * 8) * (resourceCount * 8) + unique(resourceCount) * (average_resource_name_length) bytes, since strings are cached in the constant string pool. When aclCount=50 and resourceCount=200000, M < 20MB. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
