Description
Technical field
The present invention relates to processor, more particularly to a kind of read-write operation performance optimization method and device.
Background technology
Virtualization technology is a critically important technology in computer technology, can be in same meter by virtualization technology
Multiple virtual machines are run on calculation machine hardware at the same time, an operating system is run on each virtual machine.Each operating system can phase
Mutually operate independently from the application program of oneself so that do not perceived mutually between operating system.But when the quantity of virtual machine compares
When more, the performance that different virtual machine is written and read cache buffer (Cache) operation will influence each other, because
Cache needs to handle the read-write requests of multiple virtual machines at the same time, and the access of these virtual machines differs from one another.It is for example, virtual
The size of distribution of the application program run in machine A to Cache is very sensitive, and more Cache is assigned to if virtual machine A,
Then the performance for the read-write operation that virtual machine A is showed is better；Distribution of the application program run in virtual machine B to Cache
Size it is insensitive, even if for virtual machine B distribution Cache it is more again, the read-write operation performance that virtual machine B is showed is still
Any change is not had, or even the Cache for thus giving virtual machine B on the contrary is more, causes to distribute to as virtual machine A is this
Tail off, influenced as this Cache to distribution of virtual machine A are big to the Cache of the virtual machine of the Cache magnitudes of distribution
The read-write operation performance of small sensitive virtual machine.
So if can recognize that virtual machine, the characteristics of read-write requests sent according to virtual machine, is carried out at performance optimization
Reason, then can greatly improve the performance that operation is written and read to Cache.But it in the prior art, can only at most identify reading
Write request is that some processor is sent.However, on the one hand for small virtual machine, virtual machine can in a upper period
It can operate in processor 1, may be operated in processor 2 in next period, on the other hand, for large-scale virtual machine
For, virtual machine may operate in multiple processors at the same time.So the prior art cannot identify send read-write requests be
Which virtual machine.
