Blueprint Lag

[ghost]

Description

Describe the bug

Not really a bug but the problem is that the server lags a lot when generating a blueprint. (This is the default one) there is 0 players on, always 20tps, 4gb ram etc but once you load the blueprint in, it drops to 17tps.

Steps to reproduce the behavior

Not really sure.

Expected behavior

Be optimized.

I just wish it was more optimized since we are hoping to release soon.

the last section was where the lag was.

Ignore the PlugMan

I see from the timings, it is taking 6 seconds to paste and taking 40ms of each tick. That looks like a pretty big island? Anyway, you need to lower the pasted blocks per second in BentoBox's. Here's the default:

paste-speed: 128

Maybe reduce it by half and see if that helps. You may need to reduce it to 40 or so. That will cause pasting to take longer though.

it is this island and i'll reduce it now, see if it helps

[ghost]

there it is [look in chat]

[tastybento]

What did you reduce the paste number to?

[ghost]

64, half of the original

[ghost]

just tried 40 and same results

[tastybento]

check the timings and share. Also, try a lower number even, say 32. You have a Nether and End right? Those are also being pasted.

Here are the timings

yes i do have nether and end too.

tried 32

Okay, so from that report the scheduler is taking:

12,745.57ms per - 9.50ms/0.00 per tick

i.e., about 13 seconds paste all the islands and each async bit is 9.50ms, which is less than the tick length of 20ms. You can reduce the paste number even further if you like. Alternatively, start at 1 and then move up until the maximum acceptable TPS hit.

turns out it was just a bad host, thanks for ur help
