Yusuke MIYAKE / Pepabo R&D Institute, GMO Pepabo, Inc. 2019.07.25 GopherCon 2019 Optimization for number of goroutines using feedback control Principal engineer Yusuke MIYAKE @monochromegane Pepabo Proposal 4. Evaluation 5. Conclusion �4 Agenda 1. Introduction How many is the optimal number of goroutines? Performance tuning in case of pt �7 Find Goroutines Chan Chan Search Match Performance tuning in case of pt �10 • I chose stability rather than speed… How many is the optimal number of goroutines in each case? 2. Background 1. Concurrency and complexity 2. Concurrency and

The first and most widely recognized application of blockchain is the Bitcoin [https://en Performance of a blockchain platform can be affected by many variables such as transaction size, block size, network size, as well as limits of the hardware, etc. The Hyperledger community is currently Hyperledger Fabric v1.1. The benchmarking efforts that the research team did yielded a significant number of performance improvements for the Fabric v1.1.0 release that more than doubled the overall performance
