On a 800 node cluster this takes > 2s or more to GET. > The majority of time is in the transfer of bytes. > A 3.8s call had a wait time (time to first byte) of 815ms, and content > download time of 2.98s. > We need to see if the download time can be improved. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
