"System Performance Tuning" answers one of the most fundamental questions you can ask about your computer: How can I get it to do more work without buying more hardware? In the current economic downturn, performance tuning takes on a new importance. It allows system administrators to make the best use of existing systems and minimize the purchase of new equipment. Well-tuned systems save money and time that would otherwise be wasted dealing with slowdowns and errors. Performance tuning always involves compromises; unless system administrators know what the compromises are, they can't make intelligent decisions.Tuning is an essential skill for system administrators who face the problem of adapting the speed of a computer system to the speed requirements imposed the real world. It requires a detailed understanding of the inner workings of the computer and its architecture. System Performance Tuning covers two distinct areas: performance tuning, or the art of increasing performance for a specific application, and capacity planning, or deciding what hardware best fulfills a given role. Underpinning both subjects is the science of computer architecture. This book focuses on the operating system, the underlying hardware, and their interactions. Topics covered include:

    Great case
    Color: 03-dark Grey, Size: 20" X 26" (Pack of 2)
    Love these pillow cases! FYI: 20" X 26" are PERFECT for supposed "queen size" feather pillows. 20" x 30" ones are too big and allow the feather pillow to flatten out too much. There is a bit of stretch to the cases. The "cool side" of the pillow case IS NOTICEABLY COOLER than the other side. Good zipper.

    Hmmmm not really a cooling case
    Color: 07-beige, Size: 20" X 36" (Pack of 2)
    I bought these because like many I get hot at night, right around my neck. While it's soft and satin to the touch, and cool to touch, it doors keep me cool presay. I still get hot, I flip the pillow and because it's cool, I get cooled down. Again doesn't actually keep me cool all night though.

    That I keep my head, cool
    Color: 01-grey, Size: 20" X 26" (Pack of 2)
    They are cool and that’s exactly what I wanted. Something that wasn’t hot and I’m very happy with my purchase.

    Cool, Comfortable, and Worth Every Penny!
    Color: Light Gray, Size: Standard
    I’m honestly impressed with these pillowcases! From the first night, I could feel the difference—they stay noticeably cool, which is perfect if you tend to sleep hot like I do. The fabric feels silky smooth against the skin without being slippery, and it’s really gentle on both my hair and face. I’ve also noticed I wake up less sweaty and more comfortable overall. They fit my pillows well and don’t slip off during the night, which is a big plus. After washing, they held up great—no fading, shrinking, or loss of softness. If you’re looking for pillowcases that actually help keep you cool and comfortable through the night, these are definitely worth it. I’ll be buying more!
