This causes a signficant (10%+) performance hit. On more than 4GiB, it is worsened as more extensive paging is used. If you have 1GiB or less, you should rebuild with_out_ "HIGHMEM" support which is a 1G+3G kernel, and you'll see better performance (and memory will be limited to 9...

It's all speculation at this point. But there are _several_ factors. But I'm sure the first time Intel saw AMD's x86-64/PAE52 presentation, the same thing popped into my mind that popped
