Will the LZO compression code in reiser4 be able to use multi-processor
systems?
E.g. if I've a Turion-X2 in my laptop will it use 2 threads for
compression/decompression making cpu throughput much better than
whatthe disk could do?
Compression is going in flush time and there can be more then
one flush thread that processes the same transaction atom.
Decompression is going in the context of readpage/readpages.
So if you mean per file, then yes for compression and no for
decompression.

So the compression unit is 64k for purposes of your benchmarks.
