Are you quite sure? I haven't checked to see if JiffyDOS works in standalone mode but I don't see why it wouldn't as the 1541U would still be using the JD ROM image. I'll test that later today.
When using the 1541U in standalone mode (IEC port only), there are two modes of operation.
The first is the 1541 emulation. I suppose, in this mode, it should be easy to substitute the standard 1541 ROM with a JiffyDOS configuration. Does it work? AFAIK, Gideon never tested it. Is it easy to alter the files sent to the 1541U to configure it like that? No idea.
The second mode of operation which is as a mass storage device where the 1541U becomes a sort of SD2IEC definitely does not support JiffyDOS.
In any case, even a 1541 with JiffyDOS remains considerably slower than a RAMLink.

You really should. The transfer speed increase with my JD installed 1541-II, 1581, 1571, FD-2000 and CMD HD is significant.
Loading a 16k game like Donkey Kong or Lode Runner usually takes about 3 seconds.
Be normal.
