Session lock causes ASP.Net websites to be slow

😫 Session Lock: The Hidden Culprit Behind Slow ASP.Net Websites

Are you frustrated with your ASP.Net website taking forever to load? 👀 Well, brace yourself for the revelation - session locks might be the reason behind this nightmare! 😱 But fret not, dear reader, for I have the perfect guide to help you understand and solve this pesky problem. 🧙‍♂️💻

🤔 What's the Deal with Session Locks?

Let's start with a quick primer on session locks. Every request in an ASP.Net web application is bound by a session lock, which it acquires at the beginning and releases at the end of the request. 🚦 This mechanism has significant implications that can cause frustration for both your users and yourself. Here's what happens:

1. 🕑 Slow Loading Pages: Imagine a scenario where your page is taking eons to load due to a sluggish database call or any other reason. Now, just as your abandoned user decides to abandon ship and navigate to another page, they can't! 😱 The session lock slaps a "Wait" sign on the new page request until the original request finishes its agonizingly slow load. Talk about a frustrating user experience!

2. ⏰ Tortoise-like Update Panels: Another annoyance arises when your UpdatePanel takes forever to update and your user, at their wit's end, decides to seek solace on a different page. Guess what? Yep, they can't! 😭 Again, the session lock imposes its heavy hand, forcing the new page request to wait until the previous request has completed its snail-paced update. Double arrrgh!

Now that we've set the stage and empathized with your frustration, let's dive into the solutions. 💪💡

🚀 Solutions: Unleash the Speed!

1. 🛠️ Implement a Custom SessionStateDataStore: ASP.Net offers the option to create a custom session state data store. This solution, while powerful, comes with a few caveats. Finding ready-made implementations is a challenge, and there's a risk of messing up if you're not careful. However, with thorough research and careful implementation, this option can potentially skyrocket your website's performance.

2. 🚫 Cancel Previous Requests: An extreme yet effective approach involves canceling the original request when a subsequent request is received from the same user. By keeping track of ongoing requests and canceling the ones that overlap, you can prevent the session lock bottleneck altogether. It may sound drastic, but desperate times call for desperate measures! (Just ensure you handle it with care.)

3. 🙅‍♂️ Bye-Bye, Session!: If you're not heavily reliant on session state, consider bidding adieu to it altogether. Instead, hop aboard the Cache train and store user-specific state using the authenticated username or any relevant identifier. By embracing this less session-reliant approach, you liberate your website from the clutches of session locks.

🤔 Wait, Is This Really Happening?

You might find yourself wondering how the ASP.Net Microsoft team could have overlooked such a glaring performance bottleneck in version 4.0. Are you missing something obvious? Can't they simply utilize a ThreadSafe collection for the Session? 🤷‍♂️ While it may seem puzzling, it's essential to remember that software development is a complex craft. There might be reasons, constraints, or considerations that contributed to the current implementation. However, creative minds come up with fantastic solutions. Perhaps a future update will address this issue and make our lives easier. 🤞
