We are using qnet on a system with two nodes and we are sure that our hostnames are unique in our local environment. 
Communication between the two nodes should be available as fast as possible. What we see with default configuration is a
 delay of 400 msec on startup of qnet:

Jan 01 09:00:00.573    7    15     0 qnet(L4): lr_verify_my_name_and_domain(): starting resolution of our hostname hu-
omap.dis2 to ensure unique
...
Jan 01 09:00:00.973    7    15     0 qnet(L4): lr_verify_my_name_and_domain(): qnet going online

I have set the "res_retries" to 0 which reduces the delay to 200 msec. I also tried to set "res_ticks" to 0, but this 
has no effect for the initial 200 msec delay. Setting "periodic_ticks" (default 200 msec) to a lower value seems quite 
dangerous, because it has impact on all timings.

What is your advice for saving additional time on resolution stage, if we do not need a resolver at all to ensure unique
 names?
Is it possible to write an own fast resolver and set it with "resolve=" option or set "resolve=none"?
