With lots of read request, the overhead is > significant. > Like for write request, NFS should create input stream for a file and try to > share it with multiple read requests. The stream can be closed if there is no > read request for a certain amount of time (e.g., 10 sec). -- This message was sent by Atlassian JIRA (v6.1#6144)
