The load can get rather high: 1. poudriere for a desktop, so lots of ports 2. poudriere will eat swap with a bulk run with the larger ports. I've watc= hed it run out of swap then the OS killed the running processes 3. the OS is on the ssd and data (including poudriere) run on zfs. >> Doesn't swap need to be 2x RAM on a fast disk? > >No, this is really an old assumption. OK, but doesn't it need to be at least the size of RAM if for example a pan= ic happens? I thought the contents of RAM were written to swap. --=20 J. --hoZxPH4CaxYzWscb Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEE8n3tWhxW11Ccvv9/s8o7QhFzNAUFAl5FcOkACgkQs8o7QhFz NAVWYxAAjTv3+fIy40/eq4DLa2zvFjcAQNcrfHF8y3pnTJWubZJ19jaX5hgOm7wi tsqFqnQRP6rNxqBoVazSrw6piRkR3zzZnaRzugQbQcx54FglaSnBx8Jl2XYiGg4F Dnmpkv+wadxOrpqTQFP46VOQwrwolJK4G88S7PSCC44Q3scxBLKlx9QGJRU9tNLd frjjwEn6mNrtGvJLl3WEPTau01EgAdnKKZtmisLHmzQAenYp5qIW16jm0k/Wt6gF CriM6eUEwcw1O6WJqINw2yXSbQ87DauoMbtwV4kGGPE0IuOYzrfM4mBZR734mVxL kbfGsZGnu+Kr/68+MejBO+SHqAsD+L1YDROWj9udzoR9lMBvW2aGdtoEu9mLU1QB cGfnWGKS6MlnZu9bNKv1i3K3+FeushNVtOm8R0AkatXKaQZd6RCfgMF3sXVcke3u irGXdNkuu6poX970pQ/mcRRelOSulUvsnb+dRe+SRnevXffEp1YEbUlFCOnrAVLl 7NYP+Y36GBFlwroktjqxSq71PYB+d26cIZyOP8hAXGBEtsDgt48ZxatOHiY/wlMe SjijY+7TImP0WeHiz3CAo8ALNJ1FmbiVj9av9e2J+4KJwTKreDqeYNF74oT6q37L W3S3/KOMhZ5iHdGSxcwQ+ilYmYBK8pcWeme26nEIi99P8/A5W7E= =VI/R -----END PGP SIGNATURE----- --hoZxPH4CaxYzWscb--
