IPFire 2.27 Core 162.
IPFire is a lightweight Linux distribution for firewalls,
routers, and other security-sensitive appliances. The
developers have released a new version, IPFire 2.27 Core
Update 162 which will be the last version to support 32-bit
x86 machines. "Once a few releases after upgrading to Linux
5.10, we have now rebased the IPFire kernel on Linux 5.15.
Due to dropping or upstreaming our patchset this was a lot
easier than the previous step to 5.10. The new kernel is
long-term supported by the Linux kernel developers and comes
with various new drivers and performance improvements.
Noteworthy are various performance improvements on 'zero
copy' for increased throughput and lower latency; Core
Scheduling (for safer Hyperthreading), and a new drivers for
NTFS. We have continued our work to take advantage of
improvements in the kernel that help to decrease CPU usage
when forwarding large numbers of packets. In certain
environments, this enables IPFire to significantly more
throughput and lower latency since more CPU resources are
available when needed. This is the last release supporting
32-bit Intel-compatible processors - in our case i586 and
older. Having announced this plan a year ago, the time has
