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

Therefore, we usually think that disk I/O is one of the biggest factors restricting MySQL performance. For Discuz with an average daily access volume of more than 1 million PVS! Forum, due to disk I/O constraints, MySQL performance will be very low! To solve this problem, consider the following solutions: Use a RAID-0 + 1 disk array. Do not try RAID-5, mySQL's efficiency on RAID-5 disk arrays will

reflected. On systems using Intel processor hyper-Threading Technology (HT technology), there are currently two execution pipelines on each processor core. The latest multi-core processor has two processor cores on each chip. Intel pointed out that chips may have multiple cores in the future, most of which are due to higher performance and will not fundamentally increase the consumption of heat or power. Therefore, the number of pipelines will increase. According to the arithmetic recommendati

With the common X86 CPU, according to Intel's reference manual, it is based on the following three mechanisms to ensure the locking of atomic operations in multicore (Section 8.1):(1) Guaranteed Atomic Operations (Note: 8.1.1 sections are described in detail)(2) Bus locking, using the lock# signal and the LOCK instruction prefix(3) Cache coherency protocols that ensure, atomic operations can is carried
