Thanks for your reply.
Yes. I mean that; serializing all SimObjects and writing them on a disk.
Does the checkpoint latency depend on the workload behavior?
For GCC, the checkpoint takes around 10 mins for a single point,' but it takes
3 mins for MCF.
I am not sure this is normal.
Not sure we're communicating.
When starting from boot, it takes about 15mins to reach the point
where a checkpoint will be taken. *Saving* the checkpoint is quick.
Getting to the place *where* you checkpoint is what takes 15 mins
in this boot-up scenario.
If it is really taking that long actually to save, I would say
something is wrong. Are you saving over a network, e.g., to some
remote mounted file system or something? That could affect things.
