Results of my personal test this morning (on the same machine) FreeBSD: FreeBSD 3.0-SNAPSHOT (Mai 98) Linux: Suse 5.2 Test on 7461 rows FreeBSD with ...ack_delayed=1 several hours FreeBSD with ...ack_delayed=0 1m48 Linux 5m19 My personal idea on this problem: I suppose that there is a slight problem with the yard handling of the network and that this problemcan be amplified by FreeBSD. After having ran FreeBSD for years on large servers I can hardly beleive that the problem only come from FreeBSD. One of the tests that could be done would be to convert the yard database to msql and see the results. -- Didier Derny didier@omnix.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
