Wow! I'd ask just what you were > primary/secondary for, but I don't think I want to know. :-) He said he was trying to run a top-level-domain nameserver. If that means he includes the RRs for COM (and EDU, and NET) like some of the root servers do, I'm not the least bit surprised about this size. Consider: COM alone has more than 1 million domains. The July host count came up with 764019 counted and 313075 missed domains for COM, for a total of 1077094. By now probably 1.2 - 1.3 millions.) Each domain needs at least two NS records, and may need A (glue) records. Not all the RRs will be unique, but with 100-200 bytes of virtual memory needed per RR, a virtual memory size of almost 300 MByte doesn't surprise me at all. The RSS size *is* strange, though...
