Can someone confirm if this has been truly the case and popular distributions such as Debian or Ubuntu have been shipping with this? I find it hard to believe, but reality is sometimes funny, and I don't have the knowledge to verify this.
The headline is clickbait /fakenews
The sheduler calculates the estimated speedup with max 8 cores. It's not the processing itself that is locked to 8 cores max.
If you think about it, it can't even be true. Servers are running linux on 22 core intel xeons for yeeears now and AMD Threadripper with 64 cores isn't new either. Not to speak of clusters that have thousands of CPUs hooked up to each other.
