Thanks. Let me look into the ar command line switches.

​Hum, an interesting question. I didn't really notice the "2 minutes"
portion. I took a look at the ar command here:
https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.3.0/com.ibm.zos.v2r3.bpxa500/libarc.htm

And the only thing that came to my attention is that the "-r" switch adds or 
replaces one or more members __AND__ it "regenerates the symbol table".
I don't really know what this latter is doing. But it may be why the "ar"
command is taking a fairly fixed length of time (doing something with each 
member in the archive, not just the new one).​ I would likely test this by 
adding the same member to a different archive with fewer members.
