Let me give you a generic answer:

If it as much as touches the HDD during the relevant time period, then yes. In that case you should also change file system to f.ex. Smart File System (SFS), if you're still using FFS that is.

But then again, a 68060 accelerator is very expensive. Not to say outrageusly expensive, considering actual performance. I would give you bad advice if I didn't tell you to have a look at the x86 option first.

Ok, knowing that the PAR is a DSP board with IDE interface I can give you a better answer.

A faster CPU increases the transfer rates of the A1200 IDE indirectly. If my memory serves me right, transfer rates to HDD beyond 1MB/sec is not possible using a vanilla machine. The real question is if the IDE interface of the PAR is as fast as the one in the A1200 (probably).

If you're converting loads of files in a single run using the DSP, then changing to a faster filesystem (like SFS) and adding buffers with (C:AddBuffers) will probably have a huge impact.
The filehandling of SFS is so fast that it outperforms RAM: by factor two on average (excluding bulk transfer rates).

Note: addbuffers adds blocksize times specified buffers. Blocksize is often 512 bytes. You want the total number of buffers to be to equal or larger than the largest file you want to process.
Adding 500KB in buffers with a 512 byte blocksize:

AddBuffers MyPartition: 1000

Hope that helps.

Then again, if the PAR plain sucks then it won't do you any good. Back to square one.
