It depends on what very early versions of FP were doing. Without seeing your code, there's no way to tell.
For very early versions of FP, and for specific workloads, it is possible 32-bit protected-mode FP programs were slower when it came to heavy I/O via DOS calls. It is also possible that early versions of FP created much larger code that didn't fit inside the L2 cache of your system, whereas TP did. But those would be only two use cases, which isn't enough to make the blanket statement "a program run under TP7 is about three times as fast as the same program run under FP" as you did. For most compute- or memory-hungry workloads, even a suboptimal 32-bit pmode program should drastically outperform a 16-bit real-mode program
