Re: [RFC] Bumping ufs.dirhash_maxmem to a larger value?

having 1000+ files in most of them, then raising the dirhash_maxmem will be a great help for performance. I think it would be great if we can implement a automatical "suggested value" of dirhash during bootstrap stage, though, which can be overridden through sysctl.conf or subse

[RFC] Bumping ufs.dirhash_maxmem to a larger value?

axmem value to at least 32MB or 64MB. Any objections? Cons for this, discussed in -developer: - dirhash does not implements automatical mechanism to reduce memory usage in response to system memory pressure, and benefits mainly to large directories, e.g. Maildirs. Cheers, -- Xin LI
