这个是默认的：
sysctl -w net.core.wmem_max=16777216
sysctl -w net.core.rmem_max=16777216

sysctl -w net.ipv4.tcp_wmem='4096        212992        16777216'
sysctl -w net.ipv4.tcp_rmem='4096        212992        16777216'


这个是优化过后的

sysctl -w net.core.wmem_max=33554432
sysctl -w net.core.rmem_max=33554432

sysctl -w net.ipv4.tcp_wmem='4096 425984 33554432'
sysctl -w net.ipv4.tcp_rmem='4096 425984 33554432'

sysctl -w net.ipv4.tcp_fastopen=1


不知道是心理作用还是啥，没执行前是稳定6-7W，执行过后到9W了

心理作用，物理物理不好在优化也没用

线路是CN2 GIA，物理应该是没问题的...

First we need to do some kernel settings for performance and raise ulimits.
sudo nano /etc/sysctl.conf
Copy this at end of then file and save and close.

1. net.ipv4.tcp_keepalive_time = 90
   
2. net.ipv4.ip_local_port_range = 1024 65535
   
3. net.ipv4.tcp_fastopen = 3
   
4. net.core.default_qdisc=fq
   
5. net.ipv4.tcp_congestion_control=bbr
   
6. fs.file-max = 65535000

复制代码

Then run this command to edit limits.conf
sudo nano /etc/security/limits.conf
Copy this at end of the file and save and close.

1. * soft     nproc          655350
   
2. * hard     nproc          655350
   
3. * soft     nofile         655350
   
4. * hard     nofile         655350
   
5. root soft     nproc          655350
   
6. root hard     nproc          655350
   
7. root soft     nofile         655350
   
8. root hard     nofile         655350

复制代码

Run this to apply settings.
sudo sysctl -p

sudo nano /etc/sysctl.co ...

不知道是不是和我执行的哪个冲突了，改完后速度只剩5W+了

20w油管改完剩10w
