Since we updated our SkyFactory 3 server (recent updated added this mod) I noticed a lot of ticktime is spend by the multicrafter

If there's anything I can provide to maybe resolve this, just let me know!

What version of the mod do you have?

RebornStorage-1.10.2-1.0.0.22

Do you know how many muitliblocks there are, and of what size they are?

Would it be possible for you to do:
/debug start
wait a minute or so
/debug stop
and then send me the file in the debug folder on the server?

running /debug start crashed the server.. what's wrong with the profiling report above? I can also get you a warmroast dump

I'm also having serious performance issues aswell and I'm on singleplayer SkyFactory 3.
when I've the 7x7x7 multiblock connected to the RS network the game really starts to lagg, and if I noticed the time indication in the upper left corner, I actually see the time constantly skipping back a few seconds.

if I disconnect the multiblock from the RS network, the back timeskipping actually stops. I'm on version 3.0.6 of the SkyFactory 3 pack and it uses RebornCore-1.10.2-2.13.1.104-universal

I thought this had been fixed :/

Can you try the debug commands above and see if they work?

I crashed as soon as I started the /debug start command

Have you got a crash log I could have a look at?

this is the crash log it generated from the /debug start crash

Uhh, ok. Looks like something is breaking it. I will have to try and load up SF and track down the issue.

We're experiencing issues on our server as well. Using RebornStorage-1.10.2-1.0.1.22 through RebornStorage-1.10.2-1.0.1.27 we're experiencing long delays when joining the server and high mean tick time causing lower TPS. We have a single 12x10x12 cube. The long delay on joining the server is really off putting as it feels as if your client has crashed.

Removing Reborn Storage instantly solves above issues making it easy for us to reproduce.

Same issue here. Player had a 10x10x10 multiblock if not bigger that was timing out the server for a while everytime you loaded his/her base. I've removed the mod from my server for now in the hope this will get fixed in the next release.

If it helps, here's the stall report after connecting my 5x5 (edge dimensions; 8 of 18 pages filled with recipes, most using OreDict (see refinedmods/refinedstorage#1044 for a past performance issue with OreDict )), and then the second stall report (which kicks me out and I re-login) after I open up a Crafting Grid and it re-does the calculations again.

Seems to be eating ticks here

First Multiblock Crafter connection (happens on disconnection as well): stall-2017-04-19_08.59.45.txt
First time opening Crafting Grid after connection: stall-2017-04-19_09.00.17-1.txt
I also get stalls on server startup when the above Multiblock Crafter is connected to the RS network.

Sampler NPS when connecting 5x5 Multiblock Crafter to RS network: multiblockcrafterconnected.nps.zip

Might be similar to #32 as well. Throughout the day there will be other stalls as something in RS does a recalculation and kicks my players.

Disconnecting my Multiblock Crafter removes the stalls, including when connecting to a Crafting Grid.

Mods:

• Forge Mod Loader 1.10.2-12.18.3.2281
• RebornCore 1.10.2-2.13.5.136
• RebornStorage 1.10.2-1.0.2.29
• refinedstorage 1.2.25

For documenting reasons, let me post the thing I sent to @modmuss50 on Discord here as well:

It seems to be eating ticks when the connection changes, because Reborn Storage is rebuilding its own internal pattern list when that happens.

When the connection changes, you shouldn't rebuild your own pattern list. You only need to do that when the inventory changes.

When the connection changes, INetworkMaster#rebuildPatterns just has to be called.

Ah, ok. Sorry about being wrong :P. I will take another look.

Stall reports are gone when starting up the server and connecting/disconnecting my MultiBlock Crafter from the network, thank you!

this should now be fixed
