Single-core PC (AMD Sempron) experiencing 100% CPU usage in web browsers on antiX 23 / Debian 13
Hi everyone. I installed antiX on an old PC for basic tasks, mainly managing product listings on Mercado Libre (an e-commerce platform). However, the CPU hits 100% usage as soon as I launch any web browser (I've tried both Firefox and Falkon), making the system extremely laggy and borderline unusable.
System Specs:
CPU: AMD Sempron LE-1150 (1 core @ 2.0 GHz)
GPU: NVIDIA GeForce 6150SE nForce 430 (using nouveau open-source driver)
RAM: 1.8 GB DDR2
OS: antiX Linux (Kernel 6.6 / Debian 13 base)
I know modern web pages (especially JS-heavy platforms) are demanding, but I would like to know if there is a lightweight JS-compatible browser or any system/kernel tweak that could help render these pages without maxing out the single-core CPU.
Any tips or recommendations for this hardware? Thanks in advance!
