IEFU84 is an exit point provided by the operating system (yes - which gets invoked prior to the writing of MANY, but NOT ALL, SMF records) but the performance question is really a question of what the version of IEFU84 on this system is doing when it gets invoked. The actrual code being invoked could come from a variety of sources (IBM, in-house, vendor).
The other thing to note is that for many year now the SMF exits are actually being "managed" by the CSV Dynamic Exist function so you also need to check the PROGxx parmlib member(s) on the system and look for EXITNAMEs values that include the string 'IEFU84'. By default the IEFU84 "module" is located in LPA storage (so if you are NOT using dynamic exits it should be fairly easy to locate in a dump and check the "eyecatcher" which would lead you to the next step in the investigation. NOTE: In general the SMF "record" exit points (IEFu83/4/5) are really intended to just be a quick "peak and out" thing but there are some pretty complicated exit modules out there!!!
