🚀 Exploring Performance in .NET 9: CountBy vs. GroupBy vs. Manual Loop 🚀
As a .NET developer, I’m always on the lookout for ways to optimize performance and memory usage in my applications. Recently, I decided to test the new 𝗖𝗼𝘂𝗻𝘁𝗕𝘆 method introduced in .NET 9 alongside the traditional 𝗚𝗿𝗼𝘂𝗽𝗕𝘆 method and a 𝗠𝗮𝗻𝘂𝗮𝗹 𝗟𝗼𝗼𝗽 approach. Using a dataset of 100 random products, I analyzed their performance, memory allocation, and time complexity. Here’s what I found:
🔸️ 𝗖𝗼𝘂𝗻𝘁𝗕𝘆: (𝗡𝗲𝘄 𝗶𝗻 .𝗡𝗘𝗧 𝟵):
- Performance: Efficiently counts occurrences by criteria (in this case, name length) with streamlined syntax.
- Memory Allocation: Leverages internal structures effectively, leading to optimized counting.
- Time Complexity: O(n) — traverses the list once, making it ideal for most scenarios.
🔸️ 𝗚𝗿𝗼𝘂𝗽𝗕𝘆:
- Performance: Adds expressiveness but may introduce overhead due to grouping processes.
- Memory Allocation: Allocates extra memory for groups and final dictionary storage, leading to increased memory usage.
- Time Complexity: O(n) with additional overhead for dictionary creation, impacting overall performance.
🔸️ 𝗠𝗮𝗻𝘂𝗮𝗹 𝗟𝗼𝗼𝗽:
- Performance: Allows the most control over counting but requires more detailed coding.
- Memory Allocation: Comparable to CountBy but may have slightly higher overhead from repeated checks within the loop.
- Time Complexity: O(n) — similar traversal but with potentially slower execution due to conditional checks.
🔻 Conclusion:
With CountBy, .NET 9 introduces a sleek new tool for efficient and simplified counting, especially suited for large datasets. Can’t wait to see how it holds up in more complex applications and explore all the new features in .NET 9!
