Hello Charlie,
my question is why one thread connection's speed is too low , one
thread's speed has affect the business code's write.
thanks a lot , i'm try local ping and remote ping . 2 result has Four
times the difference .
1)local ping result is:
64 bytes from 192.168.0.226: icmp_seq=796 ttl=64 time=0.048 ms
64 bytes from 192.168.0.226: icmp_seq=797 ttl=64 time=0.051 ms
64 bytes from 192.168.0.226: icmp_seq=798 ttl=64 time=0.050 ms
2)remote ping result is:
64 bytes from 192.168.0.226: icmp_seq=724 ttl=64 time=0.212 ms
64 bytes from 192.168.0.226: icmp_seq=725 ttl=64 time=0.214 ms
64 bytes from 192.168.0.226: icmp_seq=726 ttl=64 time=0.216 ms
but i had other test , on the remote pc , i set the code test 40
thread(the remote pc has 40 thread cpu) , result is 280000/second , the result
shows more connection can improve the speed , but single connection's speed
fixed at 7000/second
notes: the remote client pc's ifconfig result , i had change other on pc ,
192.168.0.169 pc is win10 notebook ,cpu is I7 7200 , test speed is 5000/second
