Hello,
my workstation with 16GB, running eclipse, jboss, postgresql, KDE, thunderbird, and two bhyve linux guests (one running skype and the other pgbouncer) was having performance problems. Viewing/deleting messages in thunderbird took 2-3 seconds and getting worse, opening web pages on firefox was slow, the system was slow. There was constant disk activity and swaping. Most of the swap (4GB) was used. So I though of buying more more RAM, I added another 16GB, totaling to 32GB and the system at first seemed OK, but later started to behave slowish again. Again there was swapping, and constant disk activity, I could hear the disk every time I clicked on a email. The Inactive memory was always more than 20GB!!!
So I turned off swap. I had tried this before with the 16GB but failed. This time worked. And one day after the system seems and is much more snappier.
So, what's the deal with swap? And free memory , Inactive memory? Lots of oldish posts about it, few solid answers.
I have been running FreeBSD since version 2 IIRC, now I am on 11.1-RELEASE.
