for the moment, c&d are separate yes. I'll look into lvm
also depending on the size of your files, they could be a few mb or afew gb in size.. adjsut the drive readahead size.

i.e hdparm -a /dev/sdd will show a result.. its probalby 256. Jack that up to 16384 i.e hdparm -a 16384 /dev/sdd so its doing by far less reads when its grabbing data for distribution. this value can be tune/adjusted for whatever your traffic/source files are like. Makes a world of a difference on large files.

Also blockdev command works great too, shorter versionof using hadparm. blockdev --report will give some information on blocksize, make the readahead a multiplier of the blocksize.
