Why?, due to limited write cycles?

As long as it is a modern SSD (years) or one of the old ones one with a
sandforce controller (OpenBSD dev let me know about that) then it has a
good 20% extra space above it's listed gigabytes reserved unusable for
wear levelling meaning this is a non issue even when full?

Unless he's worried about not being able to wipe the swap?

This is blocked by a proper fix for #617253. Ideally, mupdf would start
to provide a shared library (#719351) and commit to a somewhat stable
API. mupdf needs to get in a better shape before zathura-pdf-mupdf can
be packaged.

yes, at least for the still open issues it might be a good idea to tag these
too, and prefer the more general solution of running autoreconf.

That's one reason, but the one I was thinking of was the shocking
performance.  I accidentally disabled tmpfs on /tmp on my main
system with an SSD rootfs a few months back and was wondering
why I was experiencing such slow builds, desktop freezing for
seconds at a time, and other intermittent stalls.  Turns out it
was thrashing the SSD since /tmp was on the rootfs.  Enabling
tmpfs on /tmp resolved the problems, changing the performance
from dire to excellent.  (I have the swap on a RAID1 LVM LV on
fast HDDs).  This is a system with 8 cores @4GHz, 16GiB RAM,
over 16GiB swap, so should be pretty performant, yet /tmp on an
SSD made it crawl and freeze continually.

This is purely down to the slow write speed of the SSD I have
(Intel 320 128GB).  If you have a faster SSD, maybe it won't be
an issue, but given the amount of junk being written to /tmp
when running a desktop environment and applications, from dozens
of tmp files and sockets to streaming video, it's likely it will
make a significant difference to make /tmp a tmpfs or HDD
filesystem.

Roger

Interesting, have a look if it states the write access time spec in the
datasheet (if available) of that SSD? Though when I've looked for
write access time on off the shelf SSD drives it usually only mentions
throughput or reading.

Do you know if it slows the build if you use it for the source code? If
your not sure it's a sandforce or has similar wear levelling then
obviously don't try it in case you wear it out, though as it's your
root I don't suppose you will try it.

He said this was the Intel 320 Series 128GB drive. As far as I know
there is no officially 128GB model of that drive, but the 120GB model
(that being the advertised capacity after overprovisioning et cetera)
was reviewed in depth by The Tech Report back in 2011:

http://techreport.com/review/20653/intel-320-series-solid-state-drive

The article includes spec-sheet information and detailed benchmark
results. Glancing over them again, I'm not surprised by this described
result from that drive; there are other SSDs that might do much better.

Very nice indeed.

There's an extra patch at 

  https://github.com/ajtowns/apt/commits/better-pdiffs-dk

that makes a couple of minor cleanups in rred.cc. I think there's a few
more to do, but I got confused as to how the pkgAcqIndexMergeDiffs stuff
works, and will need to print that out to grok it, I expect...

Ah, nice, that seems like it should make it backwards compatible in
practice.

It looks to me like dak and reprepro are the only tools that generate
pdiffs currently, fwiw.

You are correct--it is indeed 120GB, my mistake.

I'm not sure if it's just the write speed.  It's also reading stuff back
from /tmp and the rest of the rootfs so it may just be a pathological
workload.  That said, I would have classed it as "very light"--/var,
/home and the build chroots etc. are all on a separate RAID/LVM array,
so /tmp was the sole part of the rootfs being actively written.

It would be interesting to have further data from users who could try
running with /tmp on the rootfs SSD and on a tmpfs (with or without
the swap on the SSD).


Regards,
Roger

My swap, /tmp, /boot, /usr, and / are all LVM logical volumes, on a
volume group backed by two identical 256GB SSDs in RAID-1 via mdraid,
and I haven't noticed any issues. All other filesystems (/var, /opt,
/home) are on a separate volume group backed by RAID-5 mechanical
storage.

However, not only does the RAID-1 question introduce another variable
and likely improve performance, these drives were specifically chosen
because they were top performers in their capacity class at the time -
and with SSDs, higher capacity generally performs better anyway. So this
may not be a particularly valuable datapoint.

Flash is basically probabilistic storage and you need extra space to
ensure that the probability your data is stored remains high, and a
(possibly trustworthy) controller with algorithms in front to help
with that. Check out Bunnie's talk at 30C3 about SD cards where he
mentioned a 16GB flash device with the controller only saying it was
128MB in size (IIRC). I assume similar things apply to SSDs/NAND etc.
