If your simulation is using vehicle speed deviations (active by default), I recommend that you use the latest development version which supports option --vehroute-output.speedfactor This reproduces the same vehicle speeds as the original run and should thereby reduce discrepancy.
There are other reasons for the discrepancy (i.e. https://github.com/eclipse/sumo/issues/3024). If you can provide a small scenario that shows a strong difference between original run and re-run, please send it my way. regards, Jakob Am Mo., 4.
