Well, if you don't like it, don't run it :-) Really, mDNSResponder's memory usage is rather average - consider that of named: ... total kB 36556 - - - or of ypbind: total kB 24264 - - - I don't think it is worthwhile expending development effort on tweaking mDNSResponder's memory usage, as it causes no actual problems, and howl is now end-of-life, having been replaced by avahi. |

Of which >10MB anonymous mapping and ~1.3MB stack. These numbers seem to be too high for a small program like mDNSResponder Steps to Reproduce: 1. 2. 3.
