How to reproduce the performance issue

Its just me and 1 other friend playing on the server and using the same network.

We just converted over to AE2 from Refined Storage because I wanted to take advantage of some of the amazing features of AE2s autocrafting. But upon transferring our massive storage and testing it out it seems to have a massive impact on the servers performance, mainly when we go to craft a stack of items from a terminal. The server will lock up for a few seconds and if I craft more than one stack that will increase how long the server will take to catch up.

Its a very simple network still, it just has a massive amount of disk drives, but with the size of our storage this was the only real way of dealing with this that I could come up with.

does anyone have any suggestions on how I could fix this issue?

20 256k item disks
120 64k item disks

Can you take the Spark profile while you are crafting the items?

I have already transferred everything back to RF because it wasn't really playable but im sure someone could reproduce this with 900,000 items in storage.

Without a spark profile there is very little (=nothing) we can do. (or a clear reproduction path, i.e. world save)
