[Monetdb-developers] do_not_use_posix_fadvise

Hi,

What is the rationale to enable or disable fadvise explicitly?

do_not_use_posix_fadvise = uname(&ubuf) == 0 && strcmp(ubuf.sysname, "Linux") == 0 && strncmp(ubuf.release, "2.4", 3) <= 0;

Answers as "it doesn't work" will not satisfy my hunger to this answer; because I do see a completely different performance upon manual changing this variable.
