Sorry to disappoint you, but no, this isn't I/O. You have just shown
that a LLVM build touches more mmap'd pages.

rsync vs. rcp
I got used to rsync's -v --progress option so much that I used it
instead of rcp even to simply copy files across the network. I dont
like software that doesnt talk to me! :-) I like the percentage bar
that --progress gives!
To my surprise, I found that, when dealing with 1GB+ files, rsync is
4-5 _times_ slower than rcp.
Yes, I know that rsync is optimized for sending deltas to a file

[External] Re: .Internal(quit(...)): system call failed: Cannot allocate memory

enough memory to work with.
When I run your GitHub issue example on a machine with around 500 Gb
of RAM it seems to run OK; /usr/bin/time reports
2706.89user 161.89system 37:10.65elapsed 128%CPU (0avgtext+0avgdata 92180796maxresident)k

So the memory footprint is quite large. Using gc.time() it looks like
about 1/3 of the time is in GC. Not ideal, and maybe could be improved
on a bit, but probably not by much. The GC is basically doing an
adequate job, given enough RAM.
If you run this example on a system without enough RAM, or...

LZO compression?
Hi,
I don''t know if this has been discussed before, but have you thought
about adding LZO compression to ZFS?
One zfs-fuse user has provided a patch which implements LZO compression,
and he claims better compression ratios *and* better speed than lzjb.
The miniLZO library is licensed under the GPL, but the author
specifically says that other licenses are available by request.

Ultimate Linux Box (was RE: optimal windows R machine)
Well, maybe this is sort of related...
Eric Raymond has written an article for the Linux Journal on how to build an
Ultimate Linux Box. You can find the whole thing at
http://www2.linuxjournal.com/cgi-bin/frames.pl/articles/style/0014.html
The machine is said to compile the Linux 2.4.9 kernel in 1 min. 50 sec. I
wonder how long it might take to build R on this beast...
Cheers,
