MODS/WRITES with ZFS compression
It would seem that using ZFS with compression could theoretically yield some amazing write performance but I haven't done any testing myself yet. Any figures or observations here?
CACHE COMPRESSION?
I'm not sure what they meant there because I have seen that ZFS uses ARC for relinquishing memory to cache However, the memory relinquishing algorithm was less than desirable for database apps . But cache compression was to minimize the memory footprint of the DS entries within the FS cache which sounds great, if it were possible, for large databases.
