Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
The embodiment of the invention discloses a kind of cpu performance method of adjustment, shown in Figure 1, the method includes：
The load information of S101, acquisition system；
Specifically, in the operating system course of work, can mainly be adopted by system file acquisition system load information
The collection load information related to CPU operations.
For example, for Linus operating systems, its ruuning situation can change in real time, the system under some Run-time scenarios
Load can be very big, and the load of system is very small under some Run-time scenarios.By the procfs file system in system,
The system load information of correlation can be got.For example, proc/loadavg files are read in Linus systems can obtain system
Average load.
S102, according to the load information, judge the load condition of the system；
Specifically, the system load information to gathering is analyzed, can therefrom know that running situation, i.e. system are born
Lotus state, specially judges that system is to be in low load condition in higher load condition.If system load is higher, really
Recognize system and be in higher load condition；If system load is relatively low, confirm that system is in low load condition.
If the system is in higher load condition, performs step S103, adjust the CPU of the system in high-performance
State；
Specifically, in embodiments of the present invention, CPU have two in performance state, one kind is high performance state, and another kind is
Power save mode.When judging that system is in higher load condition, in order to ensure system process task as early as possible, when shortening user's wait
Between, CPU should be adjusted and be in high performance state.Now, CPU plays maximum performance, shortens the response time, with quick process task
For the purpose of.
If the system is in low load condition, performs step S104, adjust the CPU of the system in energy-conservation shape
State.
Specifically, if it is determined that system is in low load condition, the task of now system treatment is less, or task is simpler
It is single, it is not necessary to which that systematic function too high can meet user's request, at this moment should adjust CPU and be in power save mode.Now, CPU
Performance is turned down, suitably slows down task processing speed, extend the response time, for the purpose of energy-conservation.
It should be noted that with reference to above-described embodiment, above-described embodiment technical scheme can be applied into arbitrary CPU
Can adjustable operating system, automatic real-time adjustment of the realization to operating system performance.Further, with reference to above-mentioned technical side
Case, further can also carry out more accurate quantitative adjusting according to system loading state to cpu performance.
The cpu performance method of adjustment that the embodiment of the present invention is proposed, including：The load information of acquisition system；According to described negative
Information carrying ceases, and judges the load condition of the system；If the system is in higher load condition, the CPU of the system is adjusted
In high performance state；If the system is in low load condition, the CPU for adjusting the system is in power save mode.Adopt
With above-mentioned technical proposal, automated collection systems load information judges system loading state, and according to system loading state to system
Cpu performance is adjusted, and under conditions of manual intervention is not needed, is automatically obtained the adjustment to cpu performance, automaticity compared with
It is high.
Optionally, in another embodiment of the present invention, the load information of the acquisition system, including：
Task quantity information or the cpu busy percentage information of acquisition system that acquisition system is carrying out.
Specifically, the task quantity that system is carrying out, and the cpu busy percentage of current system can be reflected intuitively
The loading condition of system.For example, when system perform task quantity it is more, or cpu busy percentage it is higher when, it is believed that system bear
Carry higher；When system execution task negligible amounts, or cpu busy percentage are relatively low, can think that system load is relatively low.Cause
This, the task quantity information that be carrying out for system by the embodiment of the present invention, or the cpu busy percentage information of system is acquired, and makees
It is system load information.
Optionally, in another embodiment of the present invention, it is shown in Figure 2, it is described according to the load information, judge
The load condition of the system, including：
S202, according to the load information, obtain the load of the system；
S203, by the system load with setting load threshold carry out contrast treatment；
If the load threshold of the load more than the setting of the system, performs step S204, judges the system
In higher load condition；
If the load of the system is not more than the load threshold of the setting, performs step S205, judge the system
System is in low load condition.
Specifically, in embodiments of the present invention, the data type of the system load information according to collection sets judgement system
The load threshold of load condition.Preferably, set load threshold be with load information be same dimension, same type of data,
In order to compare.For example, it is assumed that the system load information of collection is the information of the task quantity performed comprising system, then can set
Put the task amount threshold that load threshold is performed for system.When the task quantity that system is performed is more than task amount threshold, can
To be judged as that system is in higher load condition；When the task quantity that system is performed is not more than task amount threshold, it can be determined that
For system is in low load condition.
With reference to the example above, can be according to actually used scene setting load threshold, and by by system load and load
Threshold value is contrasted, and judges the load condition of system.
For example, it is assumed that the system load information of collection is to characterize the data message that system CPU utilization rate is 80%, then can be with
The load of system is therefrom extracted for cpu busy percentage 80%, accordingly, the load threshold of setting is cpu busy percentage 70%.Pass through
Compare discovery, the load (cpu busy percentage 80%) of system then may determine that system more than load threshold (cpu busy percentage 70%)
In higher load condition.

Specifically, in embodiments of the present invention, the main path of lifting system cpu performance is to shorten the CPU response times, is made
CPU is with frequency response task requests higher, so as to lift CPU operating efficiencies on the whole.Therefore, when need lifted cpu performance
When, the CPU response times are set to the shorter very first time, CPU operating efficiencies are lifted, the problem without considering CPU energy-conservations.
For example, being 100 microseconds by setting/dev/cpu_dma_latency in (SuSE) Linux OS, cpu is reduced
Response time, now CPU operating efficiencies lifting, but power saving is not carried out.
Optionally, in another embodiment of the present invention, the CPU of the adjustment system is in power save mode, bag

Specifically, in embodiments of the present invention, the main path of lifting system cpu performance is the extension CPU response times, is made
CPU is with relatively low frequency response task requests, so that relatively low CPU operating efficiencies on the whole.Therefore, when need reduce cpu performance
When, the CPU response times are set to the second time more long, CPU operating efficiencies are reduced, CPU energy savings are made as far as possible.
For example, being 1000 microseconds by setting/dev/cpu_dma_latency in (SuSE) Linux OS, extend cpu
Response time, now the reduction of CPU operating efficiencies, fully saves electric energy.
