“.NET is a great technology that dramatically boosts developer productivity. Samsung has been contributing to .NET Core on GitHub – especially in the area of ARM support – and we are looking forward to contributing further to the .NET open source community. Samsung is glad to join the .NET Foundation’s Technical Steering Group and help more developers enjoy the benefits of .NET.” Hong-Seok Kim, Vice President, Samsung Electronics.

“.NET Core has reduced our release cycle by 20% and cost on engineering resources by 30%.” When speaking about the throughput improvements and cost savings: “Additionally, it has made it possible to reduce the number of VMs needed in production by half.”

We see throughput that is 8x better than Node.js and almost 3x better than Go, on the same hardware. We’re also not done! These improvements are from the changes that we were able to get into the 1.0 product.
