    Problem description:
    ----------------------
    - I recently updated to version 1.8.1, cleared the map , updated the plugins, but when the server went 40 + people he began to heavily lag, the average online users is within 70.
    The question is, what could cause such lag?
    ----------------------
    Server information:
    ----------------------
    I use:
    -24gb ram
    -Intel Xeon Processor
    -1gbit internet connection
    -40gb(7200) HDD
    -Ubuntu server 11.04
    -CB1188
    -Memory using 1093mb on 32 users online. But lagzz... :(

    The lag is probably being caused by your hard drive and maybe the version of CraftBukkit you are using. For starters go back to 1185 because it is a recommended build. Also, you probably need to upgrade to an SDD (Solid State Drive) instead of your regular hard drive because they are EXTREMELY fast. With so many users online, your server is CONSTANTLY writing to the hard drive and this is causing it to lag really badly when tons of people are online.

    SDD is very expencive , is there another way to remove lags?

    @XtenD Yes, SSDs are very expensive. However, they have come down in price and you only need to put your map on the SSD. This means that a 32GB SSD would be more than enough for your server.

    However, if purchasing an SSD is too expensive, you can try utilizing more of your RAM by creating a RAM disk (just Google it, there are free programs that will do what you want). However, if you are using a RAM disk, it is very easy for you to lose your entire map, so make sure you make VERY frequent backups.

    @wassilij I have heard that 1.8 is more resource intensive than 1.7 (and for that matter, every Minecraft version becomes a little more resource intensive). However, I need more information about your problem. How many users, how much RAM, what processor, and what plugins do you have? Also, are you getting any errors in your server.log file?

    I think I already know the answer to this, but is logBlock using a DB to log everything?

    Yes, MySQL on localhost.

    When serverSave runs, you will be using more of your hard drive for a short period of time. This could cause lag spikes when you have such high usage. Also, how big is/are your world folder/s

    1 Your world is HUGE, but with 70 playes that is expected. You can try using something like border guard to keep the players confined to a certain chunk of the map.
    2 Stop letting players place pisons. Make the server lag too.
    3 You do not need a SSD you'r normal HDD should be fine
    4 Something is wrong with CB1188 32 players should take up more than 1Gb of RAM, or am I wrong?

    Your world is WAY too big is your problem. Although SSDs are pretty fast when they read, writing is just as fast as a regular hard drive (which is pretty slow). With that said, if could take 10 minutes for ServerSave to finish saving your world. And by the time it finishes, you are probably saving your world again. You need to have a smaller world if you don't want continuous lag. I recommend starting a fresh world and putting up a border next time.

    A fresh world is planned for 1.9 or 1.10.

    The ServerSave takes only 10 seconds ...

    And we are a Puiblic-Server so its normal that the world is so big. (Over 10k different Users logged in since Juli)

    I dont know .. i dont want limitations in my server .. and a Border is a big i think ..

    //Edit a month ago i started a test .. old map: 14 Ticks per Second, new map: 17 Ticks per Second.

    Theres not much I can tell you. Your world is way to big to be handled well. And on top of all of your plugins, it is very difficult to pinpoint a reason for your problem. Also, you should be getting 20 ticks per second (ideally).

    wassilij

    I know that i should get 20 Ticks per Second :D

    But i can say since Build 1214 everything its better, its the nonlaggest build since 1.8.1 came out (for me).
    reaches 17 - 19 TPS

    Might be EXP ORBS. I heard that was causing some lags.

    Most likely your world size, but who knows.

    I tried the lagg with a plugin against Orbs and without the plugin, not big difference ..

    I will create a system of donations for the server, it should help collecting money for SSD. Maybe its reason of lags. Ill try it out , later :)

    It's due to 1.8, everyone must be having these problems. (block) lag at the most stupid times, random read timed outs and just an overall increase of RAM usage. my 24 slot(recommended) server used to handle 32 people with around 15 plugins.

    Now it's about to catch on fire with 15 people on.
