Otherwise, a cached list is sufficient. > For a directory of 280K profiles, the load time is close to 6 seconds on a 32 > core server. With the caching, we can get it down to as much as a few > milliseconds. > To render the cache as invalid, we inspect the last modified time of the > directory to confirm whether a reload is needed. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
