After some config file tweaks, i got a stable memory usage of about 5,5-6Mb. And that's quite stable even during peak times. Of course all in-memory caches are disabled as well as disk-caches. Squid is just running for blocking somethings and logging. Anyway, on the same machine i did the memory usage tests above, squid seems to be doing very well, stable memory use. -- Atenciosamente / Sincerily, Leonardo Rodrigues Solutti Tecnologia http://www.solutti.com.br Minha armadilha de SPAM, NÃO mandem email gertru...@solutti.com.br My SPAMTRAP, do not email it ___ bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
Re: bind memory usage
I just test bind 9.5.0-P2 and 9.5.1-rc1 Bind 9.5.0-P2 allocate over 2Gb per 10 minutes of work. Bind 9.5.1 allocate 2Gb per 30 hours. 14.12.2008, в 2:15, JINMEI Tatuya / 神明達哉 написал(а): At Sat, 13 Dec 2008 11:50:52 -0200, Leonardo Rodrigues Magalhães leolis...@solutti.com.br wrote: i'm trying to run bind 9.5.0-P2 on a very low memory system.

With the thread support BIND9 will require even more memory. yes threads are already disabled. Compilation is done this way: CONFIGURE_ARGS += \ --enable-shared \ --enable-static \ --enable-ipv6 \ --with-randomdev=/dev/urandom \ --disable-threads \ --with-openssl=$(STAGING_DIR)/usr \ --with-libtool \ --with-libxml2=no \ , \ BUILD_CC=$(TARGET_CC) \ - max-cache-size 1048576 is a meaningless configuration: Any positive values less than 2MB will be ignored reset to 2MB. (from ARM) 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.
