I have the quite computer with 2 GB RAM. At compilation with

compilation swap not released. At switching off swap as result
we get ~200 MB of "dead data" in RAM, which can be released by
rebooting. How i can resolve it?
First, if the program terminated, there is no dead data. Some
might be shown as used with utilities as top, but running 'free'
will probably show that your data is still "buffered", but
available for other programs to use.
You can run this command to see the effect of dropping cache:
free && sync && echo 3 > /proc/sys/vm/drop_caches && free
Back to dub... DMD way of managing memory is fast, at the expense
of memory. I could not really enjoy fast compile time on my 4 GB
machine either, everything changed when I switched to 8 GB.
There is an option in dub to compile every object file
separately, it's '--build-mode=singleFile'. However, it has no
tracking of updated files (as make as), so it rebuild everything,
everytime. It makes the whole process slower, but you can use it
if you run out of memory (I compiled Vibe.d on a 512 MB machine
few months ago).
