[MC] my world craftbukkit-1.12.2 burst card

• Yesterday evening, playing with my friends and my side of the world the results of card burst, rodeo cattle are inside a Move ... then I landed server, CPU found exploded. . . 100% of all card usage mstsc burst memory footprint of more than 800 MB (2G server memory)
  

  Do not ask why keep so many cattle (inadequate food phobia)

• First thought after the CPU load caused by subsequent restart of the server, CPU 70% load, but my client is still very slow
• Then we noticed the Task Manager Performance tab, which upload traffic to 2.6Mbps (server bandwidth of 5Mbps)
• At this point I think of the brain inside is not my apache was attacked, then stopped the service, but still did not flow down (windows server2012 can not see a direct flow of a program). I see a floating java there is traffic through tinder per 80-- speed of 100KB but the task manager is 2.6Mbps upload speed is not normal

• Last night no solution

• This morning I moved the server on my laptop, and then after starting the CPU load of 10% of the network is still 2.6Mbps upload tinder but tell me this thing is not high traffic really subvert my perception
  

• Then I use the service port frp penetrate out, and then use that port linked server notebook found above ... he is not good .... card
  

• It will be a CPU problem?
• Or what the problem is the network? The most curious is why the task manager but there upload speed is 2.6 tinder traffic floating window did not display this traffic? Resource Monitor is not as much traffic float
• So I guess it is not because packets are small, but each time forced to send direct (ignoring the TCP buffering), taking up network resources like a large number of small to read and write files when the hard disk will be the same card

• For over again frp not card ... the card is not because it is a CPU bottleneck?
