Simple retries can make a bad situation worse. Stop DDOSing your own API.

A linear 5-retry loop holds threads too long. Use exponential backoff with jitter and a circuit breaker. Fast-fail when a service is down to keep the rest of your site responsive.

Mixing sync EF Core calls in async actions? You're starving your thread pool.

Blocking threads for DB I/O kills scalability. Replace FirstOrDefault() with FirstOrDefaultAsync(). Go async from repo to controller. Don't use .GetResult().

Is your site lagging on cache expiry? You might have a cache stampede.

If 100 threads miss the cache at once, they all hit your DB. Solve it with double-checked locking using SemaphoreSlim. Only one thread fetches; the rest wait for the result.

Stop using new HttpClient() inside your services!

Even with a using block, you’re prone to socket exhaustion under load. The OS can't recycle them fast enough.

The fix? Inject IHttpClientFactory. Let the factory manage the handler lifecycle for you.
