Hi Guys!
I faced with problem SFP.
SFF8472 is loaded high CPU. For example , I have 6 SFP now and ~28% CPU utilization.
I noticed each SFP loaded CPU + ~4%. When plugged 24 SFP switch cannot loaded at all
cisco-3750X#show processes cpu sorted
CPU utilization for five seconds: 43%/0%; one minute: 44%; five minutes: 44%

I googled and cisco recommended using other SFP. But maybe someone known other way of workaround
