💡Blazor performance Tip

Most Blazor performance issues aren’t caused by .NET…

They’re caused by over-rendering.

In Blazor Server and interactive SSR, every unnecessary render:

• Sends extra diffs over SignalR

• Wastes CPU cycles

• Slows down your UI

💡 One simple technique can fix a big part of it:

protected override bool ShouldRender()

{

return importantStateChanged;

}

Instead of re-rendering on every state change,

you control when the UI actually updates.

📊 In real-world apps, this can reduce render cycles by 50–80%.

🔥 What most developers miss:

ShouldRender() is not just an optimization —

it’s render control.

Combine it with:

• Immutable state patterns

• @key directive

• Smaller, focused components

…and Blazor starts to feel seriously fast.

💬 If you're building dashboards, real-time UIs, or data-heavy apps in Blazor…

This is one of the highest ROI changes you can make.
