IIRC the memory requirements for dedup is something like 150 bytes per block for the DDT, meaning about 1GB per 1TB space if it's all 128kB blocks. With smaller blocks, osol gets greedy. Zil is good for write performance, but remember, osol won't use more than top half of memory size for zil, so you can probably slice it up and use the rest for l2arc.
