In particular, we identified and fixed a significant and unintuitive bottleneck in an open-source project management application and verified caching behaviour in a cloud-hosted commercial product.  ...  We postulate that multi-tier profiling, starting at the web browser, is the appropriate way to solve this problem.  ...  in place to receive log messages from these different systems, collecting and aggregating profiling information will further help the analyst understand the behaviour in the system, especially by providing  ...

Provenance-based computing

Lucian Carata, Apollo-University Of Cambridge Repository, Apollo-University Of Cambridge Repository, Andy Hopper, Ripduman Sohan
It is the contextualisation that allows tying the measurements to provenance in a meaningful way, and I look at a number of use-cases in understanding application performance.  ...  In this context, provenance can be used as part of feedback loops, with a double purpose: building software that is able to adapt for meeting certain quality and performance targets (semi-automated tuning  ...  This trades off generality and memory footprint for speed of execution.  ...
