You might want to look into something like dm-cache https://en.wikipedia.org/wiki/Dm-cache (TBH, I've not used it before, so grains of salt apply for your usecase). Putting the log on an ssd is not likely to be the solution you want; it certainly won't speed up reads. -Eric > In general I'm looking to increase (cache) the reading performance of folders with a lot of small files (emails), > for email servers. > > Feel free to let me rtfm :) > I'd gladly study the documentation / articles / benchmarks but my google-fu isn't in best shape. > > Thank you, > Mike > _______________________________________________ > xfs mailing list > xfs@xxxxxxxxxxx > http://oss.sgi.com/mailman/listinfo/xfs > _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
