[ossig] gripes about tmnet ...



Dear all,

with all those gripes about tmnet - we had it on DNS, hadn't we ? - I did a
little experiment today. No science involved.

Running tmnet's streamyx; this should be added for extra spice ... !

(This is a bit of technology here, be warned !)


Firstly, I dig-ed tmnet:

dig tm.net.my                         

; <<>> DiG 9.2.2 <<>> tm.net.my
;; global options:  printcmd
 </snip>
;; ADDITIONAL SECTION:
ns1.tm.net.my.          85010   IN      A       202.188.0.132	
ns2.tm.net.my.          85010   IN      A       202.188.1.5	
ns3.tm.net.my.          85010   IN      A       202.188.0.133	

That is, three nameservers.

Next for Jaring:

dig jaring.my        

; <<>> DiG 9.2.2 <<>> jaring.my
;; global options:  printcmd
</snip>
;; ADDITIONAL SECTION:
ns3.jaring.my.          259063  IN      A       161.142.227.17	
ns4.jaring.my.          259028  IN      A       161.142.212.17	
NS5.jaring.my.          152     IN      A       61.6.38.139		
NS6.jaring.my.          71829   IN      A       192.228.128.16	
GATE1.jaring.my.        259028  IN      A       161.142.2.17	

5 nameservers. Nothing better or worse so far.

Now, which resolve 'better' ?

I selected a random, foreign site; lets imagine I wanted to read some news
from a european site. Let's call it www.nouvelles.fr.
How do these resolvers do ?
Though I was tempted to write a script, finally I resolved this site
manually with all 8 nameservers one by one:

dig @{nameserverIP} www.nouvelles.fr

I don't say this is scientific, but striking: The times this task took the
nameservers of
tmnet: 1821, 981, 676 msec
jaring: 76, 131, 98, 69, 120 msec

You don't ask to which forwarders my named.conf points (sorry, Jaring !) ??

I spare you the comment on the cache. Try yourselves how effective the
caches are; that is how much faster it gets when you ask the same nameserver
the same question repeatedly. 
I rather give you the times for my local nameserver here, on a P75, for the
same site:

First time:
dig @127.0.0.1 www.nouvelles.fr

; <<>> DiG 9.2.2 <<>> www.nouvelles.fr
</snip>
;; Query time: 1425 msec
;; SERVER: 127.0.0.1#53(127.0.0.1)
;; WHEN: Sat May 10 23:32:06 2003

And the second time:
dig @127.0.0.1 www.nouvelles.fr

; <<>> DiG 9.2.2 <<>> www.nouvelles.fr
</snip>
;; Query time: 69 msec
;; SERVER: 127.0.0.1#53(127.0.0.1)
;; WHEN: Sat May 10 23:32:18 2003


No further comment from here. Enjoy the weekend !
