What is the difference between task and thread?
...y only use them if you want to run multiple heavy computations on multiple CPUs. For example, in Windows, a thread weighs 12 KiByte (I think), in Linux, a thread weighs as little as 4 KiByte, in Erlang/BEAM even just 400 Byte. In .NET, it's 1 MiByte!)

What is the global interpreter lock (GIL) in CPython?
...s in Python are only good for blocking I/O; your app will never go above 1 CPU core of processor usage

Difference between scaling horizontally and vertically for databases [closed]
...ources whereas Vertical scaling means that you scale by adding more power (CPU, RAM) to an existing machine.
An easy way to remember this is to think of a machine on a server rack, we add more machines across the horizontal direction and add more resources to a machine in the vertical direction.

Do sealed classes really offer performance Benefits?
...iler implementation and execution environment.
Details
Many of modern CPUs use long pipeline structure to increase performance. Because CPU is incredibly faster than memory, CPU has to prefetch code from memory to accelerate pipeline. If the code is not ready at proper time, the pipelines will ...
Is async HttpClient from .Net 4.5 a bad choice for intensive load applications?
...oduced similar results: about 10 seconds to execute using around 3% of the CPU and 30 MB of memory. The only difference between the two testers was that the multithreaded one used 310 threads to execute, while the asynchronous one just 22. So in an application that would have combined both I/O bound...

Assembly code vs Machine code vs Object code?
...ine code is binary (1's and 0's) code that can be executed directly by the CPU. If you were to open a machine code file in a text editor you would see garbage, including unprintable characters (no, not those unprintable characters ;) ).
Object code is a portion of machine code not yet linked into a ...
How is Node.js inherently faster when it still relies on Threads internally?
...ease performance because it sounds to me like you are able to max out your CPU because there isn't any threads or execution stacks just waiting around for IO to return so what Ryan has done is effectively found a way to close all the gaps.
