i was having stuttering/hanging problems. so after uninstalling reinstalling my video card drivers, removing all mods, uninstalling dayz, removing all configs, and basically wiping my computer of dayz -- i reinstalled. I had also checked my hard drive to see if it was having SMART errors but everything was fine.
i loaded an official vanilla, mod-less, dayz and walked into into a field and stood there. i used CapFrameX to record 10 minutes of data of me simply standing.
Using the software I was able to see that I was hanging exactly every 148 seconds. This happened regardless what my video settings were. Draw distance didn't matter and I didn't move a muscle. in the 10 minutes of standing, i completely hung 4 times. the total stutter was 22 seconds so approximately ~5 seconds per stutter of completely frozen dayz. i was able to install and test on both an NVME drive and classic SSD, the hangs persisted.
you can see in the clips that something seemed to be accessing the hard drive very heavily during the freeze.
in the end it forced me to uninstall all steam games and then completely uninstall and remove steam and all of its folders in the various application data and common directories. once i wiped everything out and reinstalled steam and dayz i went back into a field and recorded.
the game felt smooth and there wasn't any more lengthy 5 second hangs. however you can still see (and measure) that there is some kind of spiking happening every 148 seconds. Thankfully the game is playable again for me and I have no idea why uninstalling steam was the solution, but something is happening in that period which can cause users to hang. There are lots of search results for random hangs.
