### AI overview

This comparison measures Ubuntu 26.04 LTS, CachyOS, and Windows 11 performance on a $449 CHUWI UniBook laptop with an Intel Core 3 Wildcat Lake processor, 8GB of memory, and a 256GB NVMe SSD across various workloads.

### Source excerpt

Often times when testing different Linux distributions or comparing Windows vs. Linux it's on leading flagship desktop or server hardware, but today we are looking at the Ubuntu vs. CachyOS vs. Windows performance at the opposite end of the spectrum. With the new CHUWI UniBook $449 laptop powered by Intel Core 3 Wildcat Lake and with 8GB of system memory, here is a look at how those three operating systems compare across a variety of workloads.

### AI overview

This tutorial explains why Linux may use swap even when free RAM remains and shows how to use smem to identify processes consuming swap. It also discusses reviewing memory-heavy services and cautiously adjusting swappiness.

### Source excerpt

If you've ever looked at your server and wondered why it's using swap even though plenty of RAM is available, you're not alone. This is a common scenario on Linux systems, and it can impact performance if not addressed. Continue reading...

### AI overview

A practical guide to monitoring Linux server health through metrics that can reveal resource problems earlier than broad CPU, memory, or disk-usage figures. It discusses iowait, load average, active swap activity, and inode exhaustion, along with warning signs and follow-up investigations.

### Source excerpt

Servers give you warnings before they fail. Most sysadmins performing Linux server monitoring miss them because they're watching the wrong numbers. The metrics that actually matter are one level deeper: iowait instead of CPU percentage, active swap paging instead of memory usage, inode counts instead of just disk space. Continue reading...
