1N2071 diode speed

I found four 1N2071 diodes in my junk pile.  Apparently the 1N2071 is
an obsolete diode - Mouser doesn't carry it anymore.

I looked up the datasheet for the 1N2071.  It seems designed to
operate at 60 Hz, but didn't find any info on the maximum speed for
how quickly the diode can operate.

http://www.alldatasheet.com/datasheet-pdf/pdf/102157/IRF/1N2071.html

Can the diode successfully operate at up to 10 kHz?  I have a sinking
feeling the answer is "no".

So, how quickly CAN the diodes reliably switch?  100 Hz?  400 Hz?

Any ideas?

Thanks,

Michael
