When Windows XP launched, multi-core processors were a luxury. By the time the Pentium 4 "Prescott" chips with and early Dual Core CPUs arrived, the original kernel of XP sometimes struggled.

Using unofficial ISOs like "LSD 3.7" carries the risk of pre-installed rootkits or trojans, as the source code of the modifications is rarely transparent. Licensing:

For systems using AMD dual-core processors, patched ISOs often pre-installed the AMD Dual-Core Optimizer. This utility bypassed Windows XP’s flawed core synchronization by periodically updating the processor core time-stamp counters, eliminating micro-stutters and game-speed anomalies. 3.
