This article mainly introduces the relevant knowledge of "which performance indicators need to be tested by the server". The editor shows you the operation process through an actual case, and the operation method is simple, fast and practical. I hope this "which performance indicators need to be tested by the server" article can help you solve the problem.

1. CPU (Central processing Unit)

The CPU of a stand-alone server executes instructions such as serving web pages, running database queries, or processing calculation commands. The number of CPU and kernels affects how many concurrent instructions can be executed. CPU architecture and functions also affect the speed at which instructions are executed, especially on websites or applications that design programs around these functions.

2. Memory RAM (random access memory)

The size of the server memory affects the speed at which the server processes commands. More memory is required when dealing with more complex and multiple commands. For example, dynamic e-commerce sites, database servers, etc., need to run a variety of queries and retrieval against the database, larger memory will give you a higher performance advantage.

3. Hard disk type (such as SATA,SDD)

Solid state drives (SSD) in the server provide higher disk read / write speeds, also known as input / output (IBO) performance, than SATA hard drives. Servers with SSD read and write disks are faster, but priced significantly higher than SATA hard drives with the same storage capacity.

4. Hard disk storage space

The hard disk storage of the server is a limiting factor for the size of the local database and the local storage of files, such as images. Configuring a RAID disk array can effectively increase data reliability and read / write performance, and RAID requires more than two separate storage volumes. Storage can also take the form of network storage, such as NAS (Network attached Storage) or SAN (Storage area Network).

5. Bandwidth

The bandwidth data transfer limit refers to the amount of data that can be concurrent to your server. The price of server bandwidth is generally high, usually providing common bandwidth such as 10m, 20m, 100m and so on. Tasks such as concurrent video streaming, games and big data processing all require high bandwidth.

6. Availability

High availability (HA) of the server may refer to network and power availability, which is reflected in the managed service provider's actual record of maintenance uptime and its SLA (service level agreement) to ensure a certain amount of uptime. HA can also introduce redundancy by actively adding RAID configurations separately in the system to ensure availability and fail over in the event of isolated failures.

7. Network delay

Network latency is the millisecond delay in sending information between the server and the user. The network delay is determined by the server provider, but it is affected by the distance between the server and the user and the quality of the network. For example, renting a HK server to reduce latency, the server supplier deploys the CN2 dedicated line connecting Chinese mainland to Hong Kong, which is currently a faster and more stable line for Chinese mainland access, which can provide lower latency and better network experience.
