Firstable my Varnish version
varnishd (varnish-2.0.4)
Linux Kernel 2.6.18-028stab070.14
I'm really new to Varnish. I want to configure it in my way, tunning some
parameters but I don't know how. I have this setup:
DAEMON_OPTS="-a :80 \
        -T localhost:6082 \
        -f /etc/varnish/default.vcl \
        -u varnish -g varnish \
        -w 100,2000 \
        -s file,/var/lib/varnish/varnish_storage.bin,2G"

Theorically, with -w 100,2000 I'm telling to Varnish to increase its
defaults values for thread_pool_min,thread_pool_max and yes, when I check
stats with I can see the changes. Previously, I have reboted
varnish daemon. 
But How can I increase thread_pool_max? I was able to change in admin
console, but when I reboot service, the param backs to its default config
Thanks people!
