yes threads are already disabled. Compilation is done this way:

i do RTFM :) .... and on the options section, max-cache-size
description, there's nothing about that. But if you say so, i'm sure
it's there somewhere :) I have done a quick search on 9.5 ARM and really
didnt find it .....
anyway, i successfully found that validation on the code ...
dns_cache_setcachesize and DNS_CACHE_MINSIZE ..... anything smaller than
2Mb is replaced by 2Mb. Anyway, even the 1Mb being meaningless, it would
force the DNS_CACHE_MINSIZE (2Mb) to be used and not the default one
which is 32Mb. Even if the 1Mb parameter is ignored, the 2Mb would be
something to me, comparing to 32Mb default one.
anyway, thanks for the tip. I would never realize that.
