Hi, I'm looking into my big performance issue, as i can get big lag with an i3 2130 2x2(HT)x3.4Ghz - 16 Go DDR3. I took timings during this awefull lag and go this: Somebody was flooding the server using chestshop. I use iconomy & chestshop, i have the same economy on several server, so i use MySQL. I have two issues, MySQL query are in the main thread, so every query block the main thread. Second issue, Iconomy put a LOT of query for doing pretty nothing. For exemple, if i try to buy something without having enough money, i get this: Its like 8 blocking query just to ask if a player have enough, this should need one asynchrone query. For simply taping /money player: And if i buy something in chestshop: 18 blocking query, and i only logged the select, nice Do you know any good Iconomy/ChestShop plugins who don't attack server's performance?
