PostgreSQL Introduction and performance improvement of PCIe SSD

In the relational database area, PostgreSQL is a very popular open source database software. Since its release in 1996, it has accumulated nearly 20 years of practical experience, both in PostgreSQL itself and in community ecology. Not only small and medium-sized enterprises, many large industry customers will also use PostgreSQL to build their own database system. This article focuses on PostgreSQL and compares the SAS disks in the PCIe SSD (this art

Must SSD be PCIe for enterprise-level servers?

I talked to users and vendors about how SSD (solid state drive) is used, I found that most people think that server SSDS must be ultra-high-performance SLC (single-layer unit) PCIe flash cards manufactured by manufacturers such as Fusion-IO, micron, Virident, or LSI. Although most people know that the mainstream SAS or SATA interface SSD is in the 2.5 inch format, they seem to think that these devices are o

files are in use. DiskSim is initially separated from a large, system-level simulator, so it can be easily transplanted to the entire system simulator (such as porting to SimOS ). What DiskSim Does Not Do?DiskSim only simulates and reports storage subsystem performance-related aspects. It does not simulate the behavior of other computer system components, or the interaction between components and the storage system. DiskSim simulates the performance of the hard disk system, but does not save th

Performance comparison of mechanical HDD SSD USB drive

in sequential read and write performance, sequential reading can reach the 82.4mb/s, basic and mechanical hard disk performance level, the random read and write performance slightly improved, not very obvious. Considering the high requirements of TC for Random Read and write performance, the USB drive with 3.0 interface is still difficult to meet the performance requirements.2.3 Test Result AnalysisCombined with the above test results, slow write speed is the main performance bottleneck of the
