so after some investigation loading and unloading mods i have found that sync pipes is causing lag and rubberbanding on my server.

Is the lady constant or does it happen with saves? 

lady i guess you mean lag, its constent and ive had to switch it off sadly.

Yup I meant lag (autocorrect). Did it get worse with more pipes or did it just happen? 

it just happened and without them no lag

I second this.   Major lag with about 325 pipes active.  No issues with less than 100 pipes active.  

Server FPS is jumping all around from 16 to 35 and AI lag and rubber banding while SyncPipes is loaded.

Server FPS is consistent at 40-50 with no AI lag or rubber banding while SyncPipes is unloaded.

It is understandable for what it does and its complexities...this is more of a confirmation of lag issues.

Heya, I've had a few more reports of lag. Looking into the transfer routines to see what I can do. 

Same at our server .. They nerved the flowrate to max 10 items/sec in toptier to make it playable, because of the lag and a max of 300 pipes.

I hope there is some new version on the way before they shut sync pipes down, we all love the mod so much.

There is also a problem with composters. Box pickles ->pipe "single stack" config and filter pickles-> composter with 1 stack of pickles in it. -> pipe "multi stack" filter fertilizer -> box 

The composter when it fills up after a lower level of pickle stack. it also start to fill others stacks till all stacks are full, and fertilizer got popped out of composter because there is no place for it.

You can fill composter on auto ( multi stack + filter pickles) with 1 stack fertilizer in it, but than you need to clean out the fertilizer manual out of it.

Any news on when we can expect a update/fix
