Abstract
The invention discloses a low-delay application-oriented RHEL server tuning method, which comprises the following operation steps: preparing a server, wherein the memory of the server requires that each channel is at least provided with one DIMM memory bank; the server installs an operating system RHEL; BIOS adjustment: CPU Turbo mode to raise the main frequency of the processor and disable Turbo mode if there is jitter delay; various energy saving measures are turned off. The method of the invention enables the system to work in a high-performance mode by changing the starting configuration in the system, can effectively improve the performance of network communication between systems, improves the network performance, shortens the transaction delay and meets the low-delay requirement of users.
Description
Technical field
The present invention relates to server technology testing evaluation field, be specifically related to a kind of towards the low RHEL server tuning method postponing application, relate to network-in-dialing performance related content between hardware.
Background technology
At present, in fields such as frequent transaction (sequencing transaction), market data publication, data exchange processing, live signal and graphics process, very harsh requirement is had to network delay.
In financial services industry, time delay is the important performance measurement index of disposal system.Time delay low meaning can receive the request of client in time and process, and feed back to client's result, time delay greatly then can cause Fail Transaction or suffer a loss.
RHEL, the i.e. abbreviation of Red Hat Enterprise Linux are the linux systems of Red Hat company.This series comprises three versions: Red Hat Enterprise Linux (Server including virtualization), Red Hat EnterpriseLinux Virtualization Platform.
Under RHEL system, operating system has and oneself arranges, and can directly use for great majority application, but still more difficultly meets financial field real-time high frequency transacting customer demand.
Summary of the invention
The technical problem to be solved in the present invention is: the present invention is directed to above-mentioned existing problem, the object of this invention is to provide a kind of towards the low RHEL server tuning method postponing application, instruct manufacturer by the method, user carries out tuning to existing equipment, realize equipment minimumization time delay.
The technical solution adopted in the present invention is:
Towards the low RHEL server tuning method postponing application, described method operation steps is as follows:
Prepare server, server memory requires that every passage at least configures a DIMM memory bar;
Server installing operating system RHEL;
BIOS adjusts:
CPU Turbo pattern, improves processor host frequency, if find that there is jitter delay, and disable Turbo pattern; Close various conservation measures.
Normal login system, write tuning strategy:
For RHEL system, editor/boot/grub/grub.conf file, adds nosoftlockup, intel_idle.max_cstate=0, mce=ignore_ce kernel is capable;
Wherein: nosoftlockup prohibits the use soft-lockup detecting device;
Intel_idle.max_cstate=0 forbids intel_idle;
Mce=ignore_ce forbids error correction function (ce:corrected errors);
Preserve above-mentioned strategy, reboot system.
Amendment irq parameter, fill order service irqbalance stop (closing interrupt balancing service).
If every passage only configures a DIMM memory bar, adopt 8Dual Rank 1600MT/s UDIMMs, the delay of a clock period can be reduced.
Beneficial effect of the present invention is:
The inventive method, by starting configuration in change system, makes system works at high performance mode, can the effective performance of network-in-dialing between elevator system, improves network performance, shortens time delay of concluding the business, meet user's low latency requirements.
Embodiment
Below in conjunction with embodiment, the present invention is further described:
1, testing apparatus selects NF5270M3 (tide No. 2 rack-mount server), configures as follows:
Processor:
Rack server selects E5-2690 (8c 2.9GHz) or E5-2643 (4c 3.3GHz);
Internal memory:
1) every passage at least configures a DIMM memory bar;
2) if every passage only configures a DIMM memory bar, 8Dual Rank 1600MT/s UDIMMs is adopted can to reduce the delay of a clock period;
3) as far as possible employing 8 or 16Dual Rank 1600MT/s CAS-11RDIMMs memory bar;
PCIE Gen3 slot is used to connect network interface card;
2, server installing operating system RHEL6.4:Red Hat Enterprise Linux (2.6.32-279.el6.x86_64), acquiescence normal mounting;
BIOS adjusts:
CPU Turbo pattern, improves processor host frequency, if find that there is jitter delay, and disable Turbo pattern; Close various conservation measures;
3, normal login system, write tuning strategy:
For RHEL:Red Hat Enterprise Linux (2.6.32-279.el6.x86_64) system, editor/boot/grub/grub.conf file, add nosoftlockup, intel_idle.max_cstate=0, mce=ignore_ce kernel is capable, wherein:
Nosoftlockup prohibits the use soft-lockup detecting device;
Intel_idle.max_cstate=0 forbids intel_idle;
Mce=ignore_ce forbids error correction function (ce:corrected errors);
4, above-mentioned strategy is preserved, reboot system;
5, irq parameter is revised, fill order service irqbalance stop (closing interrupt balancing service).
Below test result before and after change:
Before tuning:
Ping value min/avg/max/mdev=0.150/0.209/0.243/0.025ms, on average in about 200uS progressively tuning test result
After two-server BIOS tuning: Ping value min/avg/max/mdev=0.113/0.141/0.156/0.011ms, at about 110uS;
Adjustment two-server Linux Kernal (linux kernel) parameter restarts rear Ping value min/avg/max/mdev=0.039/0.052/0.062/0.006ms, about 52uS;
Ping value after adjustment two-server interrupt parameters, about min/avg/max/mdev=0.039/0.045/0.053/0.005ms, 45uS.
Aforementioned tuning method is effective, postpones accounting in server system postpones very little between network interface card and mixed-media network modules mixed-media.
Above embodiment is only for illustration of the present invention; and be not limitation of the present invention; the those of ordinary skill of relevant technical field; without departing from the spirit and scope of the present invention; can also make a variety of changes and modification; therefore all equivalent technical schemes also belong to category of the present invention, and scope of patent protection of the present invention should be defined by the claims.
