Embodiment Construction

[0023] Below in conjunction with specific embodiment the present invention is further described:

[0024] 1. The test equipment is NF5270M3 (Inspur 2-way rack server), and the configuration is as follows:

[0025] processor:

[0026] Choose E5-2690(8c 2.9GHz) or E5-2643(4c 3.3GHz) for rack server;

[0027] Memory:

[0028] 1) Configure at least one DIMM for each channel;

[0029] 2) If only one DIMM is configured per channel, the delay of one clock cycle can be reduced by using 8Dual Rank 1600MT / s UDIMMs;

[0030] 3) Try to use 8 or 16Dual Rank 1600MT / s CAS-11RDIMMs memory modules;

[0031] Use the PCIE Gen3 slot to connect the network card;

[0032] 2. Server installation operating system RHEL6.4: Red Hat Enterprise Linux (2.6.32-279.el6.x86_64), default normal installation;

[0033] BIOS adjustment:

[0034] CPU Turbo mode, increase the main frequency of the processor, if there is a jitter delay, disable Turbo mode; turn off various energy-saving measures;

[0035] 3...

Abstract

The invention discloses an RHEL server adjusting and optimizing method facing low delay application, which comprises the following steps: preparing a server wherein a memory of the server requests that at one DIMM memory bank is configured for each channel; mounting an operation system RHEL on the server; BIOS (basic input / output system) adjusting: in a CPU (central processing unit) Turbo manner, improving a processor main frequency and if shake delay occurs, disabling the Turbo manner; closing various energy saving measures. According to the method, by altering starting configuration in the system, the system works at a high performance manner, the performance of network communication among the systems is effectively improved, network performance is improved transaction delay is shortened and a low delay requirement of a user is met.

Description

technical field [0001] The invention relates to the field of server technology testing and evaluation, in particular to a low-latency application-oriented RHEL server tuning method, and to content related to network connectivity between hardware. Background technique [0002] At present, in the fields of high-frequency trading (programmed trading), market data release, data exchange processing, real-time signal and graphics processing, etc., there are extremely strict requirements on network delay. [0003] In the financial services industry, latency is an important performance metric for processing systems. A low delay means that the customer's request can be received and processed in a timely manner, and the processing result can be fed back to the customer. If the delay is large, the transaction will fail or suffer losses. [0004] RHEL, the abbreviation of Red Hat Enterprise Linux, is the Linux system of Red Hat. The series includes three versions: Red Hat Enterprise L...
