That is most likely because update-manager etc a lot of RAM (not all at once but they have a high change in ram/s)
Or at least my RAM usage graph wiggles a lot more when update-manager/ apt-get is running so I assume this is the case.

High CPU usage + high RAM usage = stuttering - at least for me.

Try running some programs that take CPU usage up to 100% and then start firefox and open office at the same time.
