Hi Eliot
We had this same issue with base r11.6 WAAE install. Always on the first autorep the response time was very slow, after the first autorep is was faster. There is a missing index in r11.3.6.0 which is fixed in incremental 1 -
Refer RO73603.txt, this issue was item 57 in the fix list for incr1.
57. AUTOREP -D RESPONSE TIME BAD
In a heavily loaded instance, when you issued the autorep command
with the -d option, it stopped responding and timed out. In r11.0,
there is an index on the ujo_proc_event table that begins with the
joid column , was missing in Relase 11.3.6
We also have a slow autorep response time in our non-prod environment primarily due to EEM configuration and volume of users. This is separate issue, the r11.3.6 incr1 fixed the slow response on autorep which occurred before we loaded up the EEM database.
Hope this helps
