So, you may expect it to happen next year or so.
This change is not a part of Fedora 33 but it was put up for discussion. Before you get outraged, do keep in mind that Intel is ending legacy BIOS support in 2020. Dropping legacy BIOS support (not this time)įedora developers were also discussing dropping legacy BIOS support and go with UEFI-only approach. This feature is getting quite popular and if I remember correctly, Manjaro Linux 20 also uses it. Fedora 33 will use animated background that will change the color shades based on the time of the day. This is not a serious change but a little eye candy is not a bad deal. You may also find some touchpad gesture options for switching workspaces. There will be some performance improvements and visual changes to it. And, Fedora 33 does feature it in the new release. GNOME 3.38 and all the visual changes it brings Default wallpaper in GNOME 3.38 This should serve to make Fedora more resistant to a couple further classes of runtime attacks. Improved hardening for 64-bit ARM devicesįedora 33 changes enables support for newer ARMv8.3~8.5-level code hardening features in order to enhance the security. This systemd service provides network name resolution. In that effort, Fedora 33 is going to use systemd-resolved by default. Standardizing reduces behavior differences between different Linux distributions. systemd-resolved enabled by defaultįedora is trying to standardize on upstream systemd service. In practice when not used at all, feature owner has experienced ~0.04% overhead. If the workload never touches swap, this overhead is the sole cost.
Zram has about 0.1% overhead or ~1MiB/1GiB. But it is at least an order of magnitude faster than drive based swap. This means swap-on-zram is not as effective at page eviction as swap-on-drive, the eviction rate is ~50% instead of 100%. The zram driver starts to allocate memory at roughly 1/2 the rate of page outs, due to compression. The system will use RAM normally up until it’s full, and then start paging out to swap-on-zram, same as a conventional swap-on-drive. So when the RAM is full and the system needs more memory, instead of using swap partition, Fedora will use the zram device (usually under /dev/zram0). Due to compression, it uses half as much memory as its size. Swap on zRAM by defaultįedora 33 will utilize zram instead of swap partition by default. Keep in mind that you can still change the default text editor in terminal if you don’t like Nano.
