marble pawn !timings

Info: timings

The "timings" system within Spigot/Paper is incredibly inaccurate for use with Citizens, and cannot be used to diagnose any issues related to Citizens. It notably blames Citizens for a significant amount of entity-related lag (that isn't in any way caused by Citizens).

For accurate timings, you need a Java profiler. There are a variety of profiler options (WarmRoast, YourKit, VisualVM, ...), but the simplest to use on a Spigot server is a plugin named "Spark" that embeds WarmRoast, which you can find here: https://www.spigotmc.org/resources/spark.57242/.

To get a spark report, type /spark sampler, then replicate lag issues (for no more than about a minute), then /spark sampler --stop, and post the link it gives you.

Info: logs

Please post your full latest log file.

Background Info: One of the most helpful tools to identifying the source of a problem is your server logs file! Logs contain all sorts of important information like server and plugin versions, any error messages, and a lot more important information (More Info).

How To: Your log can be found in the logs folder within your server folder. The most recent log is a text file labeled latest.log. To get help using these logs, please open that file in a text editor and copy all of the text, then open https://paste.denizenscript.com/New/Log and paste the text into the box on the page. Then click "Submit" and copy the URL and paste that back into this channel.

Please do not upload the file to Discord or to other pastebin services, use the log pastebin linked above.

if I set it to more seconds, will that work?

is a bedwars server do you still support 1.12.2?

jolly umbra May 30, 2023, 9:30 PM

#

Using 1.12.2 is a bad idea regardless of what your server is, but yes, there is limited support

#

Updating to a recent version is strongly recommended, though

last widget May 30, 2023, 9:30 PM

#

normally bedwars servers are 1.8.8 or 1.12.2, I have never seen a bedwars on 1.19.4

last widget May 30, 2023, 9:30 PM

#

jolly umbra Updating to a recent version is strongly recommended, though

for bedwars? hahaha no thanks

#

my other servers are at 1.19.4 rest assured, only bedwars will be 1.8 or 1.12.2

jolly umbra May 30, 2023, 9:33 PM

#

It being bedwars shouldn't have anything to do with it

#

You can easily allow older versions to join if you want to

Either way, ^

Timings is inaccurate for Citizens specifically (and in general, Paper is planning on replacing it), should provide a spark report

last widget May 30, 2023, 9:34 PM

no /timings paste?

jolly umbra May 30, 2023, 9:34 PM

#

last widget well mush is giant and is 1.8, hypixel too

I mean, what other servers do doesn't decide what your server does - Hypixel likely writes their own server software

#

Using these ancient versions is a massive security risk, and there's really no reason to be doing that as you can easily let older versions join and restore old PVP if you want to

certain plus I like to mirror myself on successful servers, and then I will be 1.12.2, it needs to be spark can't it be timings?

jolly umbra May 30, 2023, 9:35 PM

#

last widget no /timings paste?

Nope, should use spark (which is what Paper themselves are going to be replacing it with)

last widget May 30, 2023, 9:37 PM

finally sorry for the inconvenience and thank you

jolly umbra May 30, 2023, 9:37 PM

#

last widget certain plus I like to mirror myself on successful servers, and then I will be 1...

Big servers likely have a team of developers actively fixing exploits to use these older versions - blindly mirroring other servers isn't a good idea; some might even be running a modern version while allowing older clients themselves

#

Like, unless you have an actual reason to be using a version from several years ago, you should really update :p - we're happy to help with that in #1027976885520584814 if you'd like

#

Either way, no worries :D - if this is resolved then

it seems that the problem is back to 26%, I can't even log into the server and it looks like this

#

I will download spark if it is better for you

jolly umbra May 30, 2023, 9:43 PM

#

As that info box/Paper mentions, Timings is just outright wrong sometimes, especially about Citizens

#

So yeah, need a spark report

last widget May 30, 2023, 9:43 PM

#

ok

#

there are no players online and look at the CPU

#

86% CPU '-'

#

jolly umbra May 30, 2023, 9:51 PM

#

Based on that log your server doesn't seem to be lagging at all, it's spending most of it's tick time sleeping (I.e. has nothing to do) - as you can see the TPS is basically 20 as well

#

Are you experiencing any actual lag?

last widget May 30, 2023, 9:53 PM

#

I'm noticing only the tps like this when it is 1.12.2 and the tps should be 20.20.20 with 0 players

#

I will test recommend the Citizens

#

without the plugin
