TW slow to process zypper dup??

et al: Just reporting a "seat o the pants" impression that TW is very slow in running zypper dup . . . in comparison to my Leap 15.5, and my two Gecko rolling editions . . . not bringing in the Manjaro, the Bookworm, and the Sid editions on my '12 Mac Pro. Only difference is TW is the "grub handler" system, but today, running "195" packages and #update-bootloader . . . the machine was running for approx. 1.5 hours????? The difference in speed is "palpable" . . . in terms of running time consumed vs the Gecko systems. F
