Obviously = no > such problem with amd64? on amd64 when maxdsiz not set it stops at 512 limit but soon you set it to = 1G =20 it appearently is able to use more this is not the case on i386 - but I=20 would say don't worry about it on i386 your machine could hang at boot when setting maxdsiz higher than=20 installed physical memory but that never happened to me with amd64 I have some server running squid for caching perfect with 4, 8 and 16G of R= AM=20 I set maxdsiz do 3G on machines with 4Gigs of RAM but I do not run anything= =20 else so then I adjust cache_mem with maximum_object_size_in_memory to use t= he=20 most possible amount of memory without doing swap.=20 anyway you set it in boot.loader there is no need to compile something into= =20 the kernel =2D-=20 Jo=E3o A mensagem foi scaneada pelo sistema de e-mail e pode ser considerada segura.
