Hello,
I asked Charlie Favell in z/OS BCP System Test about RESMIL... A slightly
different perspective. Are you using MIM's MII to manage global ENQs and
by association GRSRNL=EXCLUDE? If so, global ENQs are a rare thing and you
shouldn't be concerned about performance. Maybe try RESMIL(10).
Hello,
Based on the lack of warnings in the following page in the GRS Planning
Guide (
http://pic.dhe.ibm.com/infocenter/zos/v2r1/index.jsp?topic=%2Fcom.ibm.zos.v2r1.ieag400%2Ftunring.htm
), and some customer experience, I don't think that RESMIL=0 or OFF will
severely impact your CPU

Anthony,
If you have DB2 in that plex, I would think twice (or thrice) about increasing
the resmil value, as DB2 does heavy enqueue activity. I remember one
presentation (I think it was at share or maybe another conference), where
someone from IBM GRS presented the following item:
Company A
Yes RESMIL(5) will reduce cpu consumption, it will also potentially cause
performance delays to your jobs, as each system will hold the enq request for a
minimum of 5 ms. If you have any applications that generate alot of enqueues,
that need to be sent through the ring, they will run longer.

It is a while since there had been any discussion of appropriate values of
RESMIL and its effect on CPU consumptiom. It appears that there was general
concensus that RESMIL(OFF) would be a bad idea, and that RESMIL(0) would be
best since it should be managed dynamically.
