Active Benchmarking
Debugging benchmarks is something I've done for many years, and I've seen an amazing and comical variety of failure modes. The problem is that benchmark tools are often run without understanding what they are testing or checking that the results are valid. This can lead to poor development or architectural choices that haunt you later on. I previously summarized this situation as: casual benchmark
SNIA - Storage Networking Industry Association: IOTTA Repository Home
The SNIA IOTTA Repository is a collaborative effort sponsored by the Storage Networking Industry Association's Input/Output Traces, Tools, and Analysis Technical Work Group (IOTTA TWG). The primary goal of this collaboration is to create a worldwide repository for storage-related I/O trace files, associated tools, and other related information, all of which are made available free of charge to the
