Since MSMQ message interaction requires read and write operations on disks, a relatively effective method to improve MSMQ message throughput is to improve disk read and write capabilities. you can simply store MSMQ messages, logs, and other files to different disks to reduce MSMQ's I/O dependency on a disk and achieve higher read/write efficiency. because MSMQ is generally used to store stream data, it is a good option to store MSMQ in memory if the m

Queue Delay
ratio LA/R is called flow intensityIf la/r >1, the average rate at which the bit arrives in the queue exceeds the rate at which the queue is transferred, the increase in the queue tends to be unbounded, and the queuing delay tends to be infinite. Therefore, there is a golden rule in traffic engineering: The flow intensity can not be greater than 1 when designing the system.If la/r ,

When I finish writing a TCP Service, do I really want to immediately test the performance of this service? What kind of request processing can it handle? What is its performance. I believe the following small tool can help you with your small business. It is a small tool based on beetle. You only need to set the parameters to perform a simple throughput performance test on a TCP Service.
This tool can set the number of connections to the sent data
QPS:Query rate per second (Second), the number of response requests per second, which is the maximum throughput capacity.QPS = REQ/SEC = Request Number/secQPS statistical methods [general use Http_load for statistics]QPS = Total Requests/(total number of processes * Request time)QPS: Number of times a single process has succeeded in requesting a server per second

A very simple and easy-to-use approach has recently been used to solve the problem of an insert throughput on the business, which is summarized here.First we make it clear that the insert throughput does not actually refer to the IPs (insert per second), but rather the RPS (effect rows per second).Next we say batch insert, in fact, as the name implies, is bulk INSERT. This optimization idea is very basic, t
Maximum TCP Throughput = Valid data for a RTT transfer/RTT
line Efficiency = maximum throughput/channel bandwidth
Channel efficiency can be understood as: the ratio of the bandwidth that is actually utilized to be provided.
So you can see a problem.
In a TCP connection, the channel bandwidth is 1gb/s, the sending window is fixed at 65535B, and the end-to-end delay is 20ms. What is the maximum
Based on traditional project management such as PMBOK, Prince2, and cmmeThroughput (throughput)You do not know much about it. However, I am confident that as the concept of lean continues to expand, the throughput will be more concerned.
