I have recently (following wblock's articles) performed a "buildworld" on my desktop, and then on a laptop I am just bringing out of the ground. I was absolutely astounded.... I did put the following in my /etc/make.conf before doing any of the below: //-----------Begin /etc/make.conf------------ CPUTYPE?=native WITH_NEW_XORG=yes MAKE_JOBS_NUMBER=8 WRKDIRPREFIX=/usr/obj/PortsWorkingDir //-----------End /etc/make.conf----------- The WRKDIRPREFIX (from a answer I received in this mailing list), is so that my ports and kernel are built in ram and not to the SSD until they are complete. I have /usr/obj mounted in tmpfs.....I have 32Gb of ram....of which I only used 7% of tmpfs during any of the experiences below...... Experience #1 I think the idea of keeping the OS (buildworld) separate from ports (portmaster -afdB) is nothing short of brilliance. I made several mistakes in the process...as I am junior with FreeBSD...and at no time was my OS taken down. I was able to gracefully recover and continue until all was rebuilt. Experience #2 After a buildworld, my system's memory footprint dropped by a good 1/3...It sped up significantly. The I performed a "portmaster -afdB", and rebuilt all my ports and their dependencies the long way. Another dramatic drop in resources and another increase in performance. This experience was had across a desktop, and repeated on a ASUS laptop. Is this type of improvement typical? Please advise, Sincerely and respectfully, Dave
