to disk I/O constraints, MySQL performance will be very low! To solve this problem, consider the following solutions: Use a RAID 1 + 0 disk array. Do not try RAID-5, the efficiency of MySQL on the RAID-5 disk array is not as fast as you expected. ② For MySQL applications, we recommend that you use DELL R710, E5620 @ 2.40 GHz (4 core) * 2. I like DELL R710 now and use it as a akg virtualization application; ③ For a Database Server using MySQL, we reco

Storage Test A) the storage test program uses pread/pwrite for storage testing. The speed of the blockchain traversal is based on the block chain library developed by Fr.

Environment Description:A friend company performs a database migration. Due to setup problems, all database table storage engines are set to MyISAM, based on business needs,Some database tables must be: InnoDB; otherwise, transaction execution may fail and will not be effective. Therefore, change the database table storage engine from MyISAM to InnoDB,There are more than 300 tables in the database, of which nearly 1/3 need to be modified to InnoDB, and the rest will continue to use the MyISAM en

The impact of Skip and Order on the performance is measured. 7) query the performance of 100 records (that is, KB) is not sorted and there are no conditions). This test is the impact of query results of large data volumes on the performance. 8) count the total disk usage, index disk usage, and data disk usage as the test progresses. In addition, each test uses a single-process Mongodb instance and the same

Due to some work needs, ROM development on the Android platform is required. during the development process, the official documentation is very simple and there are many problems. Therefore, we need to organize the complete personal development process, share it with you. please correct me if you have any questions.To compile a custom Android ROM, the first step is to build a reasonable hardware and software development environment. I. hardware development environment: 16 GB memory or above, hig

Currently, the mainstream pseries products are p630 and p650 models. X Series: This is an Intel-Based Server series of IBM. This product line of IBM is very rich, including all levels of server products from entry level to enterprise level. In terms of server structure, there are both traditional tower and new rack

websites will no longer have functional redundancy. This significantly improves service availability. Symbiosis disadvantages: This increases the workload for system administrators. Since services all use independent infrastructure, this will bring more attention to administrators. It is difficult to maintain backward compatibility. After one year of maintenance, the API method has undergone countless changes. So when the problem occurs, they will inevitably undermine backward compatibility,

For example, while both Xeon and Opteron have built-in APIC units, it is impossible to make them work together to build an SMP system, and even if the CP

can we choose a server product suitable for enterprise development? First, it is necessary to master some server knowledge. As we all know, in enterprise operations, servers usually perform data storage, applications, and other tasks. different services have different requirements for server configuration. For example, generally, database servers have high requirements on server hard disk capacity, WEB application servers have high requirements on processors and memory, and game servers have hi

contrast, PCI and PCI-X can only be sent or received at a specific point in time, and a sending process must wait until the receiving process ends, resulting in latency. This delay will not occur when PCIe is used. Support for intel? I/O acceleration technology makes network data transmission more effectiveIntel? I/O acceleration is an upgraded platform technology that solves multiple problems that cause server I/O bottlenecks and does not need to change existing or future applications.Progra
