High-throughput and thread-safe LRU cache details This article focuses on the high-throughput, thread-safe LRU cache. A few years ago, I implemented an LRU cache for keyword search for its id. The data structure is very interesting, because the required throughput is large enough to eliminate a large amount of use.locksAndsynchronizedKeyword, the application is i

The most common problem for network administrators is the network connection problem. Maybe the computer of the company's employees cannot access the Internet, so we can detect the problem through a few simple steps, however, there is a network connection problem that makes us feel at a loss. That is, employees reflect the slow speed of the network. Because there are many factors that determine the network speed, it is impossible to detect the speed through simple operations. As a qualified ne

PS: The following are the main concepts and calculation formulas for performance testing, which are documented below: A System Swallow metric elements: The Swallow metric (pressure capability) of a system is closely associated with the request for CPU consumption, external interfaces, Io, and so on. The higher the CPU consumption of a single reqeust, the slower the external system interface and IO effect, the lower the system throughput capacity, and

perform the Iperf function test as a client at this point.1. Testing TCP ThroughputTo determine the maximum throughput of a network card, you can run the Iperf command on any client, and Iperf will attempt to send data requests to the server as quickly as possible from the client and output the amount of data sent and the average bandwidth of the NIC. Figure 1 is one of the simplest bandwidth test commands.Figure 1 Testing network bandwidth utilizati

High-throughput systemsFor example, we do projects need to schedule, each module can be multi-person in parallel multiple tasks, can also be one or more people serial work, but there will always be a key path, this path is the project duration. The response time of a system call is the same as the project plan, and there is a critical path, which is the system impact time. The critical path consists of CPU operation, IO, External system response, and

give you an example of how a small change in the JVM configuration affects the throughput of your application. Example The application we use to demonstrate that GC has an impact on throughput is a simple program. It contains two threads: pigeater– it will imitate the python's incessant ingestion of the big fat Pig. The code does this by adding 32MB bytes to the java.util.List, and then sleeps 100ms aft

); Here I am testing, is using Kafka and storm to do data transmission, Kafka has a partition mechanism, spout the number of threads according to Kafka topic number of partition To define, typically a 1:1 relationship, that is, the current topic partition number is 18, then the number of spout threads can be set to 18. Can be a little more than this, but not How many Kafka do you need? Partition you can do the test according to your needs. Find the values you need 3, the concurrent number of bol

Use batch insert to solve the insert throughput problem of MySQL. Recently I used a very simple and easy-to-use method to solve the insert throughput problem in the business. Here I will summarize it. First, let's clarify that the insert throughput is not the IPS (insert per second), but the RPS (effect rows per second ). Next, let's talk about batch insert. In f

simple Web application. Database connection pool, the connection pool configuration is unreasonable, will also become a system bottleneck.Here, the task of optimizing the system throughput is simplified to find the system bottleneck. The simplest way is to profile,jprofiler and so on the sharp weapon, hangs to the system to go to the pressure test.However, sometimes the environment of the business system is very complex, the cost of setting up a pres
