It's simply because +less care has been done on implementing what makes Linux fast: intelligent +read-ahead, carefully-tuned page cache, etc. + +There is no ground reason this can not be achieved on GNU/Hurd, it has just not +been a priority until now (first make it work, then make it work fast). We are +currently working on multi-page pager and read-ahead, which should improve this +a lot. -- cgit v1.2.3
