pixelbeat__ commented on GNU Coreutils 9.5 Can Yield 10~20% Throughput Boost For cp, mv and cat Commands   phoronix.com/news/GNU-Cor... · Posted by u/mfiguiere

The commit with more details on that perf change is: https://github.com/coreutils/coreutils/commit/fcfba90d0d27a1...

A summary of other changes just released in GNU coreutils 9.5 are:

- mv accepts --exchange to swap files

- env accepts --argv0 to override command name

- od supports half precision floating point formats

- timeout fixes various races

- chmod -R avoids symlink replacement attack

For all the release details see: https://lists.gnu.org/archive/html/coreutils-announce/2024-0...

This is not accurate, the system packages are from the CentOS binary distribution. You might be thinking of C/C++ runtime libraries, which are distributed as separate packages used by the internal ("fbcode") binaries, but system binaries link to the standard distribution.

(Hi Giuseppe!)

Right, the standard centos system binaries are used to provision services and manage hardware.

The internal services linking against the runtime libs you mention, are actually linking against about 2000 built from source packages, and are essentially a separate distro (with a distro in this sense being an ABI compatible set of libs running on a kernel)

That does not seem to be true. The hosts I'm looking at have systemd and glibc RPMs that were built on centos.org hosts, with coreutils from redhat.com. The kernel was built on a Facebook host, but that's it (of the handful of components I've spot-checked).

Use ldd on any service binary to see that it's linked against a separate distro. (It's best to use the ldd from the corresponding platform).

There are actually three distros on each host. Current runtime platform, previous runtime platform, centos platform.

It's worth noting that this discusses the centos based provisioning and hardware management platform.

The actual distribution used to _run_ all Meta backend services is completely separate and built from source (it does share the (non centos) kernel). This is done for flexibility, performance, service isolation reasons
