There is a high-speed version of the 1N4007, the UF4007 whose recovery
time is specified as 75 ns. That's pretty fast! See
<https://www.vishay.com/docs/88755/uf4001.pdf>
The regular 1N4007 is more like 30 us. Still fast.

I respectfully suggest that you do a google search for the

How fast is a PIN diode? How fast is a 1N4007 in an Alpha 87? If
you have not measured their speed, how can you make that
statement?
It is my understanding that the 1N4007 (only) IS a PIN diode and I
have used them to replace PIN diodes in relay-less 2 meter
transceivers up to 35. Watts and normal operation and power were
restored. Without failing.
