test iscsi performance

The baseline has finally been developed, the performance of the server and the ability to withstand the pressure on the Internet, not find the right test tools can be used. So I wrote a test tool based on MFC.The startup interface is as follows:After setting the parameters, run as follows:Run through the following interface:The source path is as follows: Https://

queue.%UTIL:I/O requests account for the percentage of the CPU, the higher the ratio, the more saturated the description.1. When the value of Avgqu-sz is low, the equipment utilization is higher.2. When the value of%util is close to 1%, it indicates that the device bandwidth is already fullTo determine the system bottleneck, it is sometimes necessary to combine several SAR command options.Suspected CPU bottlenecks, sar-u and sar-q can be used to viewSuspect memory bottlenecks and can be viewed

click operation, the client may make multiple HTTP requests to the server.1.2WEB Performance Test TypeStress testing: Determine the bottleneck of a system or not receive the performance points requested by the user to obtain the maximum service level that the system can provide.Load test: Continuously increase the pre

We tested the performance of Mongodb's hundreds of millions of data records and tested the following items: (ALL inserts are performed in a single thread, and all reads are performed in multiple threads) 1) General insert performance (each inserted data entry is about 1 KB) 2) Batch insert performance (using InsertBatch of the official C # client). This

First, the performance Test terminology interpretation1. Response TimeResponse time is the time it takes to start a request from the application to the last byte of data received by the client. Response time according to the characteristics of the software can be subdivided, such as the response time for a C/s software can be subdivided into network transmission time, Application server processing time, dat

This paper mainly focuses on the performance test of web system. Does not involve the concrete execution operation, just oneself to the performance test a little understanding and the understanding.The purpose of performance testing, simply speaking, is to obtain the respons

　With the rapid development of the software industry, the modern software system more and more complex, more and more functions, testers in addition to the need to ensure the basic functional testing quality, performance has been more and more people's attention. But when it comes to performance testing, many people think of LoadRunner directly. It is wrong to think that LR is equivalent to a

IOzone is a file System test baseline tool. You can test the read and write performance of file systems in different operating systems. Can be via write, re-write, read, re-read, Random read, random write, random mix, backwards read, record Rewirte, strided read, Fwrite, Frewrite, Fread, Freread, mmap, async i/0 The performan
