I have seen some people include this wait type in their list of safe-to-ignore wait types, and they reference this blog as the source:
But that blog doesn't say it is safe to ignore, it just says that is requires more research. I am working in a system that uses FTS extensively, so I am thinking this is a big issue with the overall slowness, but not sure.
Here is a ticket that says it is fixed and will be in the next version of BOL, but it isn't there yet. You would think someone could just say what it is:
Here are the top 5 waits I am seeing in the system:
Wait_type wait_time_s pct running_pct signal_pct FT_IFTSHC_MUTEX 126444.05 41.51 41.51 0.00 CXPACKET 47485.90 15.59 57.10 2.75 PAGEIOLATCH_SH 40947.25 13.44 70.54 0.20 TRACEWRITE 23805.03 7.82 78.36 0.91 BACKUPBUFFER 20058.78 6.59 84.94 2.66
Does anyone have a definitive answer on if I can ignore it, and if so, why?
