lately (past 2 days or so), my server i run has been getting very bad redstone lag, everything else is fine, no block lag or chat lag. when i use /debug clock (commandbook), i get a very detailed list of server information about the lag, the TPS is very low and i know this has to do with the redstone problem. here's one from just now Code: [INFO] Clock test result: CLOCK BEHIND [INFO] WARNING: You have potential block respawn issues. [INFO] Expected time elapsed: 5000.0ms [INFO] Time elapsed: 9492ms [INFO] Error: -47.32406236831015% [INFO] Actual clock rate: 10.535187526337968 ticks/sec [INFO] Expected clock rate: 20 ticks/sec as you can the, the TPS is very low yet while in game the only problem is redstone, what could be causing his? Server specs: OS: Ubuntu 10.04 64-Bit CPU: AMD Quad Core @ 3ghz RAM: 4GB HDD: 500GB x 2 startup command we use is Code: java -Xmx4096M -XX:ParallelGCThreads=8 -server -Xincgc -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSIncrementalPacing -XX:+AggressiveOpts -XX:+CMSParallelRemarkEnabled -XX:+DisableExplicitGC -XX:MaxGCPauseMillis=500 -XX:SurvivorRatio=16 -XX:TargetSurvivorRatio=90 -XX:+UseAdaptiveGCBoundary -XX:-UseGCOverheadLimit -Xnoclassgc -XX:UseSSE=3 -XX:PermSize=128m -XX:LargePageSizeInBytes=4m -jar craftbukkit-0.0.1-SNAPSHOT.jar nogui and the plugins we use are.. Code: iConomy, WorldEdit, obuShutTheHellUp, MyHome, MyWarp, SignColours, MCDocs, CommandHelper, PermissionsEx, LivingForest, mcMMO, MobBounty, TelePlusPlus, CommandBook, KiwiAdmin, WorldGuard, HeroChat, xAuth, iConomyChestShop, ServerSave, HeroicDeath, BananaChunk, Permissions, LWC, NoCheat would any of these plugins cause redstone lag or is there another reason? i know redstone clocks can cause lag, would be hard to find all of them though. i've tried restarting our minecraft server and rebooting the whole server itself, no luck. removed a large redstone clock, still no luck. anything else i can try? perhaps adding something to the startup command?
And you have the lasted build version? Doouble check everything to make sure you didnt mess up the start data too
yeah we have the latest build, everything is how it should be yet we're still having this problem, we're going to update to Java 7 in a bit so we'll see how that goes.
Try running your server without plugins and see if the problem persists. If not, add a plugin and see if it lags, if it still doesn't lag keep adding plugins untill it does. BTW: backup your world!
