In temporary: House windows 11 Pro ships with a security feature that can per chance severely hamper your stable-exclaim power’s efficiency. Fortunately, it is easy ample to flip off however some would possibly per chance now now not even heed it is enabled by default.
BitLocker encryption in House windows 11 Pro is designed to safeguard files and be clear it is handiest accessible by authorized people, however it comes with a steep efficiency penalty. To learn the procedure in which mighty of an affect it would possibly well per chance appreciate, Tom’s Hardware lately performed checks beneath three instances: unencrypted (no BitLocker), tool-enabled BitLocker (the House windows 11 Pro default), and hardware-essentially based entirely mostly BitLocker.
The crew dilapidated a 4 TB Samsung 990 Pro SSD working House windows 11 Pro (22H2, with all patches installed) paired with an Intel Core i9-12900K and 32 GB of DDR4 RAM for testing.
In PCMark 10’s storage benchmark, the tool-enabled BitLocker configuration resulted in a 20 p.c slowdown over the hardware variant and no encryption. A the same slowdown became observed in Crystal Disk Ticket’s random read test, and within the random write test, Tom’s seen a huge Forty five p.c efficiency hit. In DiskBench’s 50 GB copy switch test, the tool-enabled BitLocker setup became 11 p.c slower.
The suitable news is that the hardware-essentially based entirely mostly setup performed per now now not having any encryption working in any respect. Whereas you snort on having encryption, that can per chance for certain be how to accelerate.
The paunchy slate of test results would possibly per chance also be found over on Tom’s Hardware for those that want to learn more. They additionally account for uncover within the occasion that you can appreciate encryption working and disable it within the occasion you enact. In temporary, within the occasion you are working House windows 10 Pro, it doubtlessly is now now not truly enabled; within the occasion you are on House windows 11 House, it would possibly well per chance now now not be enabled; within the occasion that you can appreciate House windows 11 Pro, test attributable to it doubtlessly is enabled.
It be additionally payment noting that your mileage will fluctuate depending on what power and CPU you are working. A chip that is vastly less extremely efficient than the Intel Core i9-12900K Tom’s Hardware dilapidated would possibly per chance originate even worse.
