Symptoms
In OUD large group searches are returning etimes > 50ms
The requirement is to return 20k member group with an etime < 15 ms
The dstune utility has been used to set autotune on start-ds, and using system available memory.
The "ds-cfg-entry-cache" has also been enabled for large group type of "groupOfUniqueNames".
Below is an access log example with etime of 66ms -
