Because instruction translation or hooking introduces extra CPU cycles, highly demanding real-time applications may experience slight performance drops.
: In the context of x86 and x86-64 architectures, "cls" might stand for "cache line size." The cache line size is the granularity at which data is transferred between the cache and main memory. For many processors, this size is 64 bytes, but it can vary. Knowing the cache line size is crucial for optimizing memory access patterns in performance-critical code. cls magic x86
