Hi, I recently tested reaper and it actually helped us alot. Even with our small footprint 18 node reaper takes close to 6 hrs.<intially took 13 hrs ,i was able to tune it 50%>. But it really depends on number nodes. For example if you have 4 nodes then it runs on 4*256<vnodes> =1024 segements , so for your env. Ut will be 256*144 close to 36k segements. Better test on poc box how much time it takes and then proceed further ..i have tested so far in 1 dc only , we can actually have seperate reaper instance handling seperate dc but havent tested it yet.
