Aspect-Capable Call Path Profiling of Multi-Threaded Java Applications
A primary goal of program performance understanding tools is to focus the user's attention directly on optimization opportunities where significant cost savings may be found. Optimization opportunities fall into (at least) three broad categories: the call context of a general component may obviate the need for some of its generality; cross-cutting program aspects may be implemented suboptimally for the particular context of use; and thread dependencies may cause unintended delays. This paper enhances prior work in call path profiling[5] in several ways. First, it provides two different call path oriented views on program performance, a server view and a thread view. The former helps one optimize for throughput, while the latter is useful for optimizing thread latency. The views incorporate a typed time notation for representing different program activities, such as monitor wait and thread preemption times. Second, the new framework allows aspect-oriented program profiling, even w...
