Two sets of 50 hosts were tested. Unregistered hosts were random strings of letters, ending in '.com'. Popular hosts were chosen from Alexa.com's list of popular websites within Qatar. Ping min/avg/max/stddev = 18.415/20.941/28.789/1.983 ms Unregistered Hostnames min/avg/max/stddev = 239.634/275.962/365.393/41.064 ms Popular Hostnames min/avg/max/stddev = 23.020/35.106/409.358/54.044 ms Qtel's DNS server is caching popular results correctly and you can expect a response for most cached queries within 150ms (mean+2s.d.). That's OK, and probably unnoticeable by end users. --nigel From flyin.bbb8 at gmail.com Sat Apr 18 06:05:42 2009 From: flyin.bbb8 at gmail.com (Flyin_bbb8) Date: Sat, 18 Apr 2009 16:05:42 +0300 Subject: [Qatar-pm] [List] Qtel DNS performance In-Reply-To: <2379a820904180219n3bf2249cr9d5fc4c3d0b57059@mail.gmail.com> References: <2379a820904180219n3bf2249cr9d5fc4c3d0b57059@mail.gmail.com> Message-ID: <2165c69d0904180605y10e778ffi48e369a15b181bb6@mail.gmail.com> i think we can use this as a better alternative 193.0.14.129 ( k.root-servers.net) , can you check nigel? -------------- next part -------------- An HTML attachment was scrubbed...

Here are the results from a local copy of bind on a West-Coast USA server. Unregistered min/avg/max/stddev = 5.394/25.400/171.496/32.290 ms Popular min/avg/max/stddev = 1.497/2.213/4.106/0.510 ms I think a really well run DNS server in Qatar could respond to a cached request in less than 5 ms plus network latency, but no end user is going to care that the average DNS request is taking 25 ms rather than 35 ms, or that 95% of requests are within 30 ms rather than 150 ms. The performance of Qtel's DNS isn't bad enough for a replacement to make much difference. However, there are certain to be other applications, such as NTP, which Qtel aren't providing that could usefully be maintained by QGLUG. Andy suggested a local METAR weather archive. Any other suggestions??? --nigel From kosala.atapattu at gmail.com Sat Apr 18 11:47:27 2009 From: kosala.atapattu at gmail.com (Kosala Atapattu) Date: Sat, 18 Apr 2009 21:47:27 +0300 Subject: [Qatar-pm] [List] Qtel DNS performance In-Reply-To: <2379a820904180651o629037dfv4aee2e081e7cf6a6@mail.gmail.com> References: <2379a820904180219n3bf2249cr9d5fc4c3d0b57059@mail.gmail.com> <2165c69d0904180605y10e778ffi48e369a15b181bb6@mail.gmail.com> <2379a820904180651o629037dfv4aee2e081e7cf6a6@mail.gmail.com> Message-ID: <966e88ae0904181147h5d94f369t7e47082789960bce@mail.gmail.com> BTW, if you run a local bind in the cache mode, and point to the local DNS server in the /etc/resolve.conf, results will be much faster.
