Well we have our z15 in and running. We have been testing the System Recovery Boost on our tech lpars. What we have found makes us think we will be setting the option to BOOST=SPEED for our tech lpars. I normally define each lpar with a minimum of 1 zIIP with 1 zIIP in reserve. With BOOST=SYSTEM the 2nd zIIP is getting put online and it stays online for an hour. We really don't want to do that on our tech lpars. We may also look at this related to the other lpars as we roll this out to see what happens.
Just daydreaming here, but it would be nice if there was a time limit you could set for how long BOOST was active (unless I missed something). As I stated before BOOST was active for an hour on our tech lpars and they really don't need that BOOST for that long. From an IPL earlier today: SP01 20037 13:31:49.03 00000090 IWM064I BOOST ACTIVATED. SP01 20037 14:31:49.06 00000090 IWM064I BOOST ENDED. Thanks..

If you only want to use your existing zIIPs or available MIPS as a sub-capacity "model" (i.e. if you are not on a 7xx capacity setting) for System Recovery Boost then there is no charge.
