3. reading the third line field, i.e. the percentage R1 (for example, 6.7%us) of reading user's space occupancy CPU；
4. being successively read the corresponding CPU that occupies of corresponding process uses the field of percentage R2 and the word of memory usage amount
Section；
5. using R1, R2 and R3 as the result for obtaining overhead data.
Wherein, the control command used on different operating system is not necessarily identical, but in different operating system
On can using control command realize current system resource service condition extraction.
S14 determines encryption overhead using the first expense and the second expense.
When determining encryption overhead, it can use the first expense and the second expense directly calculated, it is specific as follows, due to
Therefore first expense utilizes second as the expense for obtaining thread and encryption thread as the expense for obtaining thread, the second expense
Expense, which subtracts the first expense, can be obtained the expense of encryption thread.Wherein, the expense of thread will be encrypted as encryption overhead；It can also
Repeatedly to extract the first expense and the second expense respectively, and calculate the average value of the first expense and being averaged for the second expense
Value, the first expense after being subtracted averagely using the second expense after being averaged, is obtained the expense of encryption thread, will encrypt opening for thread
Pin is used as encryption overhead.
Data encryption expense provided by the invention determines method, by the way that data encryption process is divided into acquisition thread, adds
Close thread and thread is sent, and the operating status at least one of controlling above-mentioned thread and data is determined according to the operating status
Encryption overhead, this method are just capable of determining that data encryption expense merely with encryption meeting, without introduce non-encrypted meeting into
Row comparison, so that fixed limit is scheduled on same target to data encryption expense really, to guarantee that all establish a capital really is under same benchmark
It carries out, the accuracy for the data encryption expense determined is higher, and this method can be avoided caused by extraneous factor really
Fixed number is different according to the benchmark of two objects of encryption overhead, influences the accuracy of determined data encryption expense.That is,
Compared with prior art, method provided by the invention can fast quantification data encryption expense, realize encryption performance expense
It is accurate to calculate, evade after calculating separately expense in different meetings the mode of comparison result again, considerably increases calculated result
Reliability and preciseness.
In the present embodiment, other than it can determine encryption overhead, it can also determine in the same way and obtain thread
Expense or send thread expense.Such as: when all threads are all run, extract the expense in current data ciphering process
A1；When encrypting thread and transmission thread is out of service, the expense A2 in current data ciphering process is extracted, is subtracted using A2
