It is beneficial to > treat this as a separate feature since > 1> The ProxyUsers is per proxyuser where as proxyservers is per cluster. The > cardinality is different. > 2> The ProxyUsers.authorize() and ProxyUsers.isproxyUser() are synchronized > and hence share the same lock and impacts performance. > Since these are two separate features, it will be an improvement to keep them > separate. It also enables one to fine-tune each feature independently. -- This message was sent by Atlassian JIRA (v6.2#6252)
