FastCache

6x-10x faster alternative to MemoryCache

TL;DR

Bascially it's just a ConcurrentDictionary with expiration.

Why FastCache is better than System.Runtime.Caching.MemoryCache and Microsoft.Extensions.Caching.MemoryCache.

• 6X faster read times than MemeoryCache.
• 10x faster wites than MemoryCache
• Thread safe and atomic writes
• MemoryCache's come with performnce counters that can't be turned off

Tradeoffs

This lib uses Environment.TickCount which is 26x times faster tham DateTime.Now. But TickCount is limited to Int32 overflow. That is why you cannot cache stuff for more than ~25 days (2.4 billion milliseconds).
