Why Your App is Still Slow After Optimization?

Sat, 30 Aug 2025 12:31:22 +0000

You have optimized your database queries, your API responds in under 100ms, and your CDN is correctly configured. Yet users still report slow load times, and performance monitoring shows latency spikes that appear without explanation.

The issue often lies outside your application or infrastructure. Two core network protocols can directly impact performance. TCP congestion control may make inefficient decisions about how data flows under varying conditions, and BGP routing can send traffic along longer, suboptimal paths across the internet.

Is FaaS the Same as Serverless?

Sun, 21 Apr 2024 10:24:46 +0000

Suppose, as a small business owner, you’ve worked hard to build an e-commerce website that showcases your unique products. Your website is gaining traction, and you’re starting to see a steady increase in customer traffic. However, with this growth comes a new challenge - scalability.

Whenever a customer clicks your site’s “Buy Now” button, your web application needs to process the order instantly, update the inventory, and send a confirmation email. But what happens when hundreds of customers start placing orders simultaneously? Your current server-based architecture simply can’t keep up, leading to slow response times, frustrated customers, and lost sales.

Why You Should Use Vectorization Instead of Loops in Python?

Sun, 14 Jan 2024 02:08:48 +0000

I’ve often come across scenarios where efficiency and speed are of the essence, especially when dealing with large datasets or complex numerical computations. One technique that consistently proves its worth in such situations is vectorization.

I’ll explain why vectorization should be your go-to approach over traditional loops in Python, especially when dealing with array operations.

What is Vectorization in Python?

Vectorization, in the context of Python, refers to the use of optimized, pre-compiled functions that can operate on entire arrays or sequences of data at once, instead of processing each element individually. This is particularly effective when using libraries like NumPy, which is designed for efficient numerical computations.

Blockchain, Cryptocurrency and Web3 Explained for Kids

Sat, 30 Dec 2023 05:05:00 +0000

🗄️ What is Blockchain?

Let’s think of blockchain as a special diary that is copied among many different computers. This diary can be used to record transactions - like person A sending money to person B.

The exciting part is that once a transaction is written in the diary, it can never be erased! And for a new transaction to be added, all the computers have to agree that it is valid. This prevents anyone from cheating or changing the records.

DevOps vs SRE vs Platform Engineering

Sun, 26 Nov 2023 06:30:56 +0000
