the problem, if the full log records, it is easy to find the problem through the log. For example, when the system goes down, the system log prints out an out-of-memory error when a method executes, and we can follow the lead and quickly locate the problem that caused the memory overflow.

The performance indicators of network products are mainly proposed in rfc2544 and rfc3511.It mainly includes throughput, latency, back-to-back, packet loss rate, new link per second, transaction processing per second, valid throughput (HTTP throughput), and maximum concurrency.
Throughput, latency, back-to-back, and packet loss rate are defined in rfc2544 and belong to 2-3 tests. The UDP data type is used in the tests. The other tests are defined in r

Overview
With the development of Web application technology and the rapid popularization of Web applications, the performance and service quality of web system becomes more and more important. Performance testing plays a more and more important role in the quality assurance of software. Performance test is to test the

Iii. Performance Testing
These classes have many different functions that can be tested. The shortlist is frequently used because it is considered to have good performance in random insert and delete operations. Therefore, the following analysis focuses on the performance of the insert operation
formal operation. For a running system, you need to obtain the system running data (such as the peak concurrency, system response speed, system load, network traffic, and the percentage of each type of requests in the total) based on monitoring). For a new system, it is better to evaluate the specific performance, because the system is usually relatively simple at this time, and the growth of data volume cannot be overnight, therefore, you can evalu
As the project is coming to an end, performance testing is required. Without professional performance testing engineers, you have to study LoadRunner on your own.
It was found that LoadRunner has many introductions to Web testing, and there are very few materials involved in

1 Performance Test process 1.1 performance test plan stage
The main work of the test plan phase is as follows:
1. Define the test object
2. Define test objectives
3. Define the Criteria for passing the test
4. Plan the Test Progress
5. Plan testing participants (requirements, development, testing, O M and config
Performance testing often verifies that the software's capabilities are reused under normal and system conditions to meet performance metrics, or that the new version is not slower than the old version. Generally also check the system memory capacity when running the program will not be lost.Method:SEI Load Test Planning processGoal: Generate a clear, well-unders

iterations), I can find that, data insertion performance may be as low as several hundred records per second during data migration. In fact, I think you can manually split the database or manually split the historical database. Do not rely on this automated sharding, because the data is placed in the correct position at the beginning, and the efficiency of the relocation is unknown. I personally think that it is more appropriate for a single MongoDB
