u're off wrong. ;-) it's not a bug. the kernel can only access approx 860mb directly. anything above that, and the memory needs to be accessed differently for the total amount of memory, using translation tables.
this leads to a performance hit as every memory access takes around 3 reads or what it normally does. so probably the only time when this pays off is when data is obtained off the memory rather than from disk (or any other storage media), eg in large databases, web servers, where the data is often intentionally placed in a "ram disk" and mounted, rather than on physical media. hope this explanation helps. any errors pls correct me. ----- Original Message ----- From: "Martin L.
