While increasing amount of features usually result in poorer performance and more memory consumption, Eclipse Photon has proven the opposite: The Eclipse Platform got faster and less memory hungry than before. This has been achieved by intensive profiling of multiple use cases and refactorings derived from the analysis.

This talk will take a look behind the scenes and shows how profiling tools can help to understand performance bottlenecks in Eclipse based products and Java applications in general. Attendees will learn about the YourKit Java Profiler tool, which while being a commercial product can be used for free on Open Source development. I will discuss some former hot spots identified in the Eclipse platform with analysis screenshots and how they got resolved.

In this session I will demonstrate how we implemented a language server for the Solidity language, the language for smart contract development on the Ethereum blockchain. The language development is based on Eclipse Xtext, which implements the Language Server Protocol (LSP). By doing so, we were able to deliver Solidity tooling for multiple IDEs at once. I will show the Solidity integration for Eclipse, VSCode and Theia, and give some understanding about the LSP. Further I will show the development of smart contracts with the means of statemachines with the integration of Solidity into the Yakindu Statechart Tools.
