This paper identifies and formalizes a prevalent class of asymptotic performance bugs called
redundant traversal bugs and presents a novel static analysis for automatically detecting …

As the use of mobile devices becomes increasingly ubiquitous, the need for systematically
testing applications (apps) that run on these devices grows more and more. However …

Determining whether a configurable software system has a performance bug or it was
misconfigured is often challenging. While there are numerous debugging techniques that …

Developers of thread-safe classes struggle with two opposing goals. The class must be
correct, which requires synchronizing concurrent accesses, and the class should provide …

The low cost of resource ownership and flexibility have led users to increasingly port their
applications to the clouds. To fully realize the cost benefits of cloud services, users usually …

Performance bugs are a prevalent problem and recent research proposes various
techniques to identify such bugs. This paper addresses a kind of performance problem that …

Modern computer systems are highly-configurable, complicating the testing and debugging
process. The sheer size of the configuration space makes the quality of software even …

Design and implementation defects that lead to inefficient computation widely exist in
software. These defects are difficult to avoid and discover. They lead to severe performance …

Performance bugs which manifest in a production cloud computing infrastructure are
notoriously difficult to diagnose because of both the difficulty of reproducing those bugs and …

Software benchmarks are only as good as the performance measurements they yield.
Unstable benchmarks show high variability among repeated measurements, which causes …
