+[[!meta title="Is the Hurd slow?"]]
+
+The Hurd is currently slower than Linux, yes.
+
+The main reason is *not* because of the overhead of RPCs. 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.
