FreeBSD 13.0-BETA2 and slow IO
I build a test system with 13.0-BETA2 and it's very slow with at least IO. Doing "portsnap auto" takes much more time than 12.2. Also when I do "rm -fr /usr/ports" with 12.2 takes 5 seconds and the same command with 13.0-BETA2 takes 100 seconds. The disks are similar 4TB HDD drives on both systems. Is this related to debug enabled in 13.0-BETA2? ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

I install 12.2 in the same system and "rm -fr /usr/ports" was fast. So it's not related to hardware. If I upgrade it to 13.0-BETA2 the same command is slow again. ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

If yes, this is known and fix is planned for BETA3 or BETA4. ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

The time to download and unpack a large port distfile (e.g. firefox) is painful. I'm hoping this is causing it as I just had the disk on my new laptop replaced 6 months ago and I was afraid that it was failing again. -- Kevin Oberman, Part time kid herder and retired Network Engineer E-mail: rkober...@gmail.com PGP Fingerprint: D03FB98AFA78E3B78C1694B318AB39EF1B055683 ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

Did someone test if this is fixed in BETA4? ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

Is this what others are seeing? I'll note that someone submitted: https://lists.freebsd.org/pipermail/freebsd-bugs/2021-March/100124.html against 13.0-BETA4 for the UFS journaled soft-updates related performance issue(s). They compared something to 12.1-RELEASE for illustration. === Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar) ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
