Pointers in C are 8 bytes instead of 4 bytes on 64bit platforms. That would account for a good chunk, as they're used not only for memory allocation, but function pointers, offsets, etc. Don't know that it would be around twice, though... Cheers -steve Jonathan Saint-Léger wrote:
I am currently doing some tests with snort and I found out that snort running on a 64bits OS seems to use on average TWICE the memory it uses on the OS’s 32bits version (I’m using Ubuntu Karmic Koala). I did my tests with and without host attribute tables, and with different search-methods: lowmem, ac,… Do somebody get the same results? I have trouble explaining it, any idea?
