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 -- olli
