Why is .NET so Insanely Fast? with Stephen Toub | Keep Coding Podcast #7
Keep Coding Podcast
In this video I will have a chat with Stephen Toub, Partner Software Engineer at Microsoft. Stephen has been a core part of the performance advancements in .NET and in this episode I will try and get his perspective on why is .NET so fast.

protobuf-net is a contract based serializer for .NET code, that happens to write data in the "protocol buffers" serialization format engineered by Google. The API, however, is very different to Google's, and follows typical .NET patterns (it is broadly comparable, in usage, to XmlSerializer, DataContractSerializer, etc). It should work for most .NET languages that write standard types and can use attributes.

.NET Core 2.1.1 comprises:

• .NET Core Runtime 2.1.1
• .NET Core SDK 2.1.301

A few of the customer-requested updates in Microsoft SQL Server 2014 SP1 are:

• Column store performance is improved when batch mode operators spill over to disk. A new XEvent provides insights into column store inserts.
• Several issues in buffer pool extension SSD configuration are addressed, including the ability to do instant initialization of the buffer pool extension file.
• Certain queries compile faster when using new cardinality estimator, and other cardinality estimation query plans are more efficient when using TF-4199. 
• The scalability benefits of two trace flags (TF-1236, TF-9024) are applied automatically.
• Backup header information retrieval works better with encrypted backups.

These are the issues addressed in 15.9.15:

• Updated signing of VC Redist packages to enable continued deployment on Windows XP. This fix may have an increased chance of requiring a reboot of the machine in order to install an updated VC++ Redistributable package.
• Fixed in issue where GoToDefinition does not work for JavaScript in script blocks of cshtml files.
• Calling pmr monotonic_buffer_resource release will corrupt memory.
• Fix for HRESULT E_FAIL build error in some C++ projects when upgrading to 15.9.13
