Abstract

The invention discloses a method for optimizing host network performance, which comprises the following steps: dividing a predetermined memory of a kernel space into a shared memory buffer area of a user space and the kernel space; reading data to be sent in a disk into the shared memory buffer area according to the instruction of an application program, and writing corresponding sending information of the data to be sent into the shared memory buffer area; and actively inquiring the shared memory buffer area according to a drive program of a network card to search the data to be sent and send the data to be sent and the sending information. The system and the method can improve the network performance in a relatively simple mode.

Description

technical field [0001] The invention relates to the Internet field, in particular to a method for optimizing host network performance. Background technique [0002] Network performance is an extremely important part of host performance, and network performance mainly includes two aspects: central processing unit (CPU) occupancy rate and throughput rate. When other factors remain unchanged, reducing CPU usage is a goal worth pursuing. Ideal network transmission performance requires reducing CPU usage while increasing network throughput. [0003] However, the CPU occupancy rate and the throughput rate are contradictory to each other. Generally, the improvement of the throughput rate is at the cost of sacrificing the CPU, which objectively requires the consumption of a large amount of CPU resources. Especially with the development of Internet technology, whether it is a terminal system or a backbone network, due to the large number of Gigabit or even 10 Gigabit routers, coupl...
