If you are not familiar with pL/proxy and PostgreSQL clusters, you can seeSkype plans for PostgreSQL to scale to 1 billion usersThis article. The following operations are performed on three different machines. The machine names of the plproxy node are p1, and those of the database node are D1 and D2.

the flagship Carro, positioning high-end installed users and VR gamers, so in with the CPU and motherboard, the balance should also be high-end CPU and high-end motherboards. 　　q:gtx1080 with what CPU? A: First of all, say GTX1080 graphics card with what processor, because GTX1080 is a top-grade new independent graphics card, when paired with the CPU, the best natural is with high-end processors. In the current high-end processor, basically is the Intel Core i7 series and the

The most popular service tools to build websites are Apache and IIS. So which performance is better between them? What is the best tool for us? I have also done some research on this issue recently. If it's based on a Linux platform, it's not necessarily Apache, because IIS can only run in Windows, and Linux+apache's overall performance, security, and versatility are stronger than Windows 2003+iis 6.0, but what's the best performance for IIS 6.0 and Apache 2.2.6 on Windows 2003 servers? I did

Profile: With the release of the Intel Pentium III processor, many new features have been brought to the program designers. With these new features, programmers can create better products for users. Many of the new features of Pentium III and Pentium III Xeon (Xeon processors) enable her to run faster than the Pentium II and Pentium II Xeon processors, which inc

However, Wei just said that the DDR4 version of ECC So-dimm, VLP RDIMM, LRDIMM and other types are also being developed, will soon be introduced. These memory are used by servers and workstations, and Wei Gang said they have been working closely with Intel, and its DDR4 memory fully supports the next-generation serve

. Disadvantages:-system administrators have a greater amount of work-because the service is based on its own architecture, the system administrator needs to be more concerned about the architecture.-Maintain backward compatibility-there are countless changes to the API approach during one year of maintenance. The problem is that these changes must not compromise backwards compatibility, or the code for each front-end site needs to be modified, and the programmer will work when all the sites are

Are data stored on disks and stored on flash cards? Does multi-threaded read/write affect performance? How can we choose a variety of data storage methods? This article will conduct detailed performance tests on different storage methods to provide you with performance test data for different storage methods. It will al
