Hi Kurt,

are you running PD also in a jail?

If not PD can be tuned by setting MFSSIZE *or* USE_TMPFS in poudriere.conf.

On my system I have good results with 8 concurrent builds and MFSSIZE=6G or 'USE_TMPFS=all'.
Fine tuning can be done with an additional SSD (look at `systat -iostat' during a build)

poudriere.conf:

# When building packages, a memory device can be used to speedup the build.
# Only one of MFSSIZE or USE_TMPFS is supported. TMPFS is generally faster
# and will expand to the needed amount of RAM. MFS is a bit slower, but is
# more mature and can have its memory usage capped.

# If set WRKDIRPREFIX will be mdmfs of the given size (mM or gG)
#MFSSIZE=4G

# Use tmpfs(5)
...
# all       - Run the entire build in memory, including builder jails.
USE_TMPFS=all
