Hi Wesley,

I used to run BIND 9.1.3 and later BIND 9.2.3 on this type of machine

cat /proc/cpuinfo

cpu             : 486
model           : 486 DX-25/33
fpu             : yes
wp              : yes
bogomips        : 18.94

cat /proc/meminfo

I remember some good reasons to change to BIND 9.2.3
I remember some times when the machine had "gone to sleep" for
a minute or two.

The machines did always come back. The reason was memory refresh
or database refresh.

I did run the machines as authoritative nameserver and as recursive
resolver. I did not use any forwarders.

There are good reasons to switch to a current version of Bind.
At least 9.3.?

Currently I am running BIND 9.4.0a5 on this machine:

cat /proc/cpuinfo

processor       : 0
cpu             : 486
model           : 486 DX-25/33

fpu             : yes
fpu_exception   : no
cpuid           : no
wp              : yes
bogomips        : 18.94

cat /proc/meminfo

It is an ancient system but works without problems. Maybe
having more memory is a difference.

Maybe your problem has to do with forwarders. I have given
up using forwarders because I cannot control them. My
resolver has been always faster without forwarders. I gained
even more speed when slaving one of the root-servers.

Kind regards
Peter and Karin
