Not all of the tests showed a horrifying performance hit, with results varying between different types of task that were being tested. Tests showed an increased in latency and a decrease in transfer rates to a degree that was noticeable without the need for benchmarking. This was not the case with hardware encryption, or no encryption. The software-based encryption - that is, what Microsoft provides out of the box in Windows 11 Pro - was found to hinder performance dramatically. The tests compared the performance differences between not having BitLocker enabled, having software BitLocker turned on, or using a hardware version of BitLocker.
In a series of tests performed by Tom's Hardware, BitLocker badly impacts upon random write and read times, thereby reducing overall system performance.
