With memory playback, the files play instantly, seeking is instant, and changes to the next track are instantaneous. I have a 32-bit Windows 7 computer (3707 JMarks) with 3 GB of memory. JRiver only uses about ~600 MB even if I'm showing 2 Gb available. My CPU goes to 14% for two seconds before dropping back to 0, but playback is instantaneous.

Are you bitstreaming, or converting to PCM? Are the files DST compressed? It's usually more problematic when downmixing from multichannel as well.
EDIT: I just realized that if they are DSF files, they will be uncompressed stereo tracks.
After checking this, it seems like the problem may only be with DST compressed tracks. (DSF is uncompressed, DST compression is optional with DFF stereo tracks)
What may also make a difference is that I have Media Center set to use the minimum ASIO buffer size (so seeking etc. should be instantaneous)

I am converting to PCM. Using ASIO with JRiver buffers set to "Minimum Hardware Size" works just fine.
It sounds like maybe DST compressed files will need to be handled differently.

If you don't receive a benefit, why not turn off the feature ??

Well in MC18 it meant that seeking was instant and disk I/O wouldn't affect playback.

If dsf isn't a problem you could consider converting them maybe?
