I have a Tinderbox that I just updated to the current RELENG_9. Following the update build times for packages have increased by a factor between 5 and 20. I.e. I have packages that used to build in 5 minutes and now take an hour. I'm suspecting the file system ever since I saw that the majority of CPU load was caused by ls when I looked at top (more than 2 minutes of CPU time were counted that moment). The majority of the time most of the CPU load is caused by bsdtar, pkg_add, qmake-qt4, etc. Without exception tools that access a lot of files. The file system on which packages are built is nullfs mounted from an async mounted UFS. I turned async off, to no avail. /usr/src/UPDATING says that there were nullfs optimisations. So I think this is where the problem originates. I might hack the tinderbox to use 'ln -s' or set it up for NFS to verify this. -- A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing on usenet and in e-mail?
