Understanding and detecting real-world performance bugs
Guoliang Jin, Linhai Song, Xiaoming Shi, Joel Scherpelz, Shan Lu · 2012
Developers frequently use inefficient code sequences that could be fixed by simple patches. These inefficient code sequences can cause significant performance degradation and resource waste, referred to as performance bugs. Meager increases in single threaded performance in the multi-core era and increasing emphasis on energy efficiency call for more effort in tackling performance bugs.
