Specific embodiment
Types of applications on mobile terminals, due to a large number of services Quick thread, causes opening using cold-start phase at present
Dynamic performance is undesirable, and then influences the usage experience of user.And in order to improve user to the usage experience of application, traditional optimization
Scheme can optimize UI layout or Optimized code structure, with this come promoted using cold start-up starting performance, reduce application it is cold
Time required for starting.However this traditional prioritization scheme produces little effect, such as may only only reduce 10ms using cold
Time required for starting, and can also consume a large amount of time and efforts of developer.
In view of the above-mentioned problems, this specification is accounted for from another angle, measured by tool, discovery application cold start-up rank
Expend that (magnetic disc i/o reads from disk the data of certain section of sector or to magnetic by instructing in magnetic disc i/o the section plenty of time
Data are written in disk section sector, instructing is usually that notice disk starts sector position, then provides needs from this initial fan
The contiguous sector number of area backward, while providing corresponding operation: it reads or writes, disk receives this instruction, will be according to instruction
Requirement, read data perhaps write data single reading according to or once to write data be exactly a magnetic disc i/o) on, the reason is that using
In cold-start phase, can there is a large amount of file read-write operations, more true magnetic disc i/o has occurred, if it is possible to it is less this
The number of a little magnetic disc i/os, has entire starting performance and is obviously improved, and then promotes the usage experience of overall applicability.
On mobile terminals, for example, the first floor system of android system is linux system, Linux file system exists
Caching mechanism (Page Cache, page cache memory, abbreviation page height is slow, is typically sized to 4K, in reading and writing of files, it
For the logic content of cache file, to accelerate the access to image on disk and data), data are read from disk every time
When, Linux file system default goes to read according to 16*4K size, and the data of reading are put into caching, if next time reads
In the buffer, then true magnetic disc i/o will not occur for the corresponding data of file, but directly read from caching, compare
In reading data from caching, data are read from disk and need to expend the more time.Assuming that the file that next time reads, in text
Part arrangement layout in, behind the file specifically read, then it by maximum probability specifically read file when just by simultaneously from
It reads corresponding data in disk to be placed into caching, to reduce primary true magnetic disc i/o.For example, for A, B two
A each 1K of file, if B comes behind A, when reading A file, the reading space of 16*4K can read from disk
It takes and reads B file corresponding data while A file corresponding data and be placed into caching, when reading B file in this way, Bu Huifa
Raw true magnetic disc i/o reads the corresponding data of B file directly from caching.
According to this thinking, if can measure using cold-start phase, required file when using cold start-up, by right
The adjustment of file layout will come together using file required when being cold-started, and using caching mechanism, can effectively reduce true
The number of real magnetic disc i/o.Because for generally apply included file, file layout substantially according to default a-z,
The sequence of 0-9 is ranked up, and irregular may be present in using file needed for cold-start phase and be applied in included file,
Such as required file is file A, file B, file C, size is respectively 1K, based on initial file layout, is added when using cold start-up
3 true magnetic disc i/os occur for file needed for carrying, if adjustment file layout, file A, file B, file C are come together,
1 true magnetic disc i/o occurs for file needed for loading when using cold start-up, it can be seen that is effectively reduced true magnetic disc i/o
Number, and then can be promoted using starting performance, reduce the time required for application is cold-started.
Based on above-mentioned analysis, this specification embodiment provides a kind of technical solution for adjusting file layout, for be optimized
Application, the corresponding file identification of required file, determines the first file identification list and second when determining application cold start-up
File identification list, wherein the first file identification list and the second file identification list can be according to the application cold start-up when institutes
It needs the corresponding file identification of file to obtain, the first file identification list and the second file identification list is integrated, root
According to integrated results, the corresponding current file layout of All Files that the application to be optimized includes is adjusted, it is subsequent to be somebody's turn to do
When using cold start-up next time, true magnetic disc i/o can be effectively reduced using caching mechanism based on file layout adjusted
Number is promoted and applies cold starting performance, reduces the time required for application is cold-started.For developer, due to not being related to
The optimization of application source code can save developer and optimize time and efforts spent by application source code.
Specifically, the technical solution that this specification embodiment provides is as follows:
Determine application to be optimized；For the application to be optimized, the application cold start-up when institute to be optimized is determined
Need the corresponding file identification of file；Determine the first file identification list and the second file identification list, first files-designated
