Would setting sector size to 4K be benefical for filesystem performance? From what I know, sector size only affect journal and metadata writes. So, should I manually set sector size to 4K or it is not worth the (minor) inconvenience? Thanks. -- Danti Gionatan Supporto Tecnico Assyoma S.r.l. - www.assyoma.it email: g.danti@assyoma.it - info@assyoma.it GPG public key ID: FF5F32A8
