if you want to get the highest income, you'd better find a conscientious mining software. The mining instry has been working for such a long time, and the service in this aspect is quite perfect
if your wireless network or network speed through router can not reach broadband speed, then it is likely that it is the problem of router
it is recommended to replace a better router or use al band router to get better service, WiFi language

Four kinds of delay in computer network are: node processing delay, queuing delay, sending delay and propagation delay
1, node processing delay
the time taken between the completion of a data change on one server and the appearance of the change on another server (for example, the time between the change at the publisher and the appearance of the change at the subscriber)
delay refers to the time it takes for a frame to go from one port on the network to another
2, network delay
network delay refers to the transmission of all kinds of data through network protocols (such as TCP / IP) in the network media. If the amount of information is too large and not limited, excess network traffic will lead to slow response of the device, resulting in network delay
3, queuing delay
delay refers to the time required for data to be transmitted from one end of the network to the other. Queuing delay refers to the packet passing through many routers when it is transmitted through the network. However, after entering the router, packets have to wait in the input queue for processing. After the router determines the forwarding interface, it has to queue in the output queue to wait for forwarding
4, delay
delay refers to the time required for a message or packet to be transmitted from one end of a network to another. It includes transmission delay, propagation delay, processing delay and queuing delay In general, we mainly consider transmission delay and propagation delay. For the case of large message length, the transmission delay is the main contradiction; When the message length is small, the propagation delay is the main contradiction
delay refers to the time interval between the first bit of a packet entering the router and the last bit outputting from the router. The time interval between sending test package and receiving data package is usually used in test. Delay is related to packet length, which is usually tested within the range of router port throughput. It is meaningless to exceed the throughput test
extended data:
definition: the time used for transmission in the transmission medium, that is, the time from the time a message begins to enter the network to the time it begins to leave the network
how to define the degree of network delay:
(the lower the network delay Ping value, the faster the speed)
1 ~ 30ms: extremely fast, almost imperceptible delay, especially smooth playing any game speed
31 ~ 50ms: good, normal game, no obvious delay
51 ~ 100ms: ordinary, confrontation game can feel obvious delay, a little pause
& gt; 100ms: poor, unable to play normally, stuck, packet lost and dropped
calculation method: 1s = 1000ms (for example: 30ms is 0.03s)
reference source:
network delay
network queuing delay
network delay
network delay
< P > network delay
A: it has nothing to do with the size of the bandwidth, and it has something to do with the arrival time and distance
the farther the distance, the greater the delay or packet loss
the general reason for the large Ping value is the problem of DNS, that is, the DNS itself given by ISP has delay
another possibility is that there is an attack, which is an intranet attack
how to solve it< The solutions are as follows:
solution:
1. ARP - A on the computer you can't get on, and check whether the Mac and IP obtained are consistent with the gateway Mac and IP
2. If not, check whether there is a MAC-IP routing device in the network, or find out the IP that initiated the ARP attack by capturing packets
3. Find out the source of the attack by some ARP checking tools, and then redo the system (the ARP sending machine may not be unable to access the network)
in fact, these phenomena are all caused by the underlying vulnerabilities, such as (ARP & # 92; ARP & # 92; ARP & # 92; ARP = # 92; ARP = # 92; ARP = # 92; ARP = # 92; udp\ TCP SYN). It is suggested that you try the immune wall. It seems that it is done by a company called patrol. It is mainly to solve the problem of internal network protocol vulnerability and Ethernet is not good at management. Owners can check online
