    I notice that whenever I run make buildworld, it is using only a single CPU. Is it possible to make it use all the CPUs?

    PF How BSD pf performance depend on CPU frequency, L2/L3 cache size

    Hi, hardware gurus! How exactly BSD pf performance (in matter of low latency, high PPS, etc) depend on bus frequency, main CPU frequency and L2/L3 cache size in multi-package (mean physical multi-CPU, like Intel E5500/5600, E5-2000 series) server systems that intend working as border firewall...

    ZFS Performance: RAIDz1 vs mirroring

    In my home PC, one of my two HDD that I have in (btrfs) RAID 0 failed. So, I am shopping for the replacement. I am planning to install FreeBSD (zfs) and set up RAIDZ (buying 3 SSDs). Now, I am reading everywhere that mirroring 2 disks (1 vdev per disk) is faster than RAIDz1 with 3 disks. And it...

    Downgrading Xorg

    Hello I recently upgraded from 10.3 to 11.1 and ever since my Xfce desktop has been behaving like a drunk laggard. Things like multiple chrome windows with a few tabs on each (say 5 to 7) causes the desktop to slow down considerably. Some websites do not even open now taking forever until I...

    Thereotical question about today's software

    Good day! I want to ask, what do you think about such problem. Or maybe this is not a problem at all? All we hear about Moore's law and it seems to work for current days. So from 90's to 2017 CPU performance, RAM capacity and HDD capacity grows in nearly 1000 times. But why all today's desktop...
