I've been using debian testing on a 4G system.

I updated from debian squeeze (which used a regular tmp partition) to
debian testing (which uses tmpfs). I use memory-intensive programs I
write myself - I know their memory usage quite a lot, and I feel the
wasted RAM by tmpfs. At first I didn't know why my programs swapped
when they didn't use to (they use close to 4G), and then I noticed
debian is assigning ~700M to tmpfs.

It's hurting even though the partition itself only has 500k used
(measured with du --max-depth=0 -h), probably because it will
partially fill up during the workload, otherwise I cannot explain the
performance difference. And, if you were wondering, it is shadowing an
explicit tmp partition I made during installation, but it's not using
systemd. So, at least without systemd, debian is not honoring fstab
entries.

Hope that bit of information is useful.
