US 8,543,907 B1 · Context-sensitive optimization level selection

Abstract

A method for selecting a performance optimization level for program code segments (e.g., JavaScript code) embedded in interactive webpages according to the origin (e.g., domain) of the webpages is disclosed. The information on historic usage behavior on webpages from the same origin is collected. The historic usage behavior can be specific to the current user or an average or aggregated behavior across many users who have visited webpages from the same origin. The historic usage information is used to select an appropriate level of optimization to achieve the maximum performance improvement for the least amount of compilation cost. The selected optimization level can be adjusted over time based on a measure of actual performance improvement resulted from the different levels of optimization that had been carried out during prior visits.

Dependent claims

A computer-implemented method, comprising:

receiving, from a server, one or more segments of program code embedded in a webpage having an origin;
receiving information on a user's prior code invocation behavior of code on webpages from the origin;
selecting a level of performance optimization for the one or more segments of the program code in advance of compilation of the segments of the program code based on, at least, the received information, and wherein the level of performance optimization specifies a type of program code compilation optimization for the one or more segments;
and
performing, by a processor, the selected level of performance optimization on the one or more segments of the program code.

A computer storage medium encoded with a computer program, the program comprising instructions that when executed by data processing apparatus cause the data processing apparatus to perform operations comprising:

receiving, from a server, one or more segments of program code embedded in a webpage having an origin;
receiving information on a user's prior code invocation behavior of code on webpages from the origin;
selecting a level of performance optimization for the one or more segments of the program code in advance of compilation of the segments of the program code based on, at least, the received information, and wherein the level of performance optimization specifies a type of program code compilation optimization for the one or more segments;
and
performing the selected level of performance optimization on the one or more segments of the program code.

2 more elements

A system comprising:

one or more processors;
memory coupled to the one or more processors and operable for storing instructions, which, when executed by the one or more processors, cause the one or more processors to perform operations, comprising:
receiving, from a server, one or more segments of program code embedded in a webpage having an origin;
receiving information on a user's prior code invocation behavior of code on webpages from the origin;
selecting a level of performance optimization for the one or more segments of the program code in advance of compilation of the segments of the program code based on, at least, the received information, and wherein the level of performance optimization specifies a type of program code compilation optimization for the one or more segments;
and
performing the selected level of performance optimization on the one or more segments of the program code.
