[gem5-users] Slow checkpoint creation

Hi everyone, I recently returned to gem5 and tried to create SimPoints for SPEC and other workloads on ARM architecture. gem5 works great as usual, but I am curious why it takes 10~30 mins to write just a single checkpoint. The simulated system has 16 GB DRAM. Typically taking a snapshot of a
