Pinpointing bottlenecks on the Samsung 9100 PRO PCIe 5.0
Looking at those jagged spikes is like trying to read a heart patient's EKG during a panic attack. I followed the approach in report #2025-MA12 on Win11 24H2 and stopped relying on single bursts, switching instead to five consecutive stress loops. Using 3DMark's statistical tools, I found the controller load peak was stuck between 0.32-0.47s, which pointed directly to an I/O scheduling bottleneck. I managed to trim the analysis latency by 17-31ms, bringing the error margin basically to zero. Then I disabled the pointless disk indexing services in Windows, and the optimization efficiency jumped by 13% - 19%. My baseline FPS finally stabilized between 58-63fps, and those random drops are mostly smoothed out. This quantitative approach saved me from a huge mistake—I realized the bottleneck was in the driver's async handling, not the hardware itself, so I didn't waste money on a new drive.
