How might I tweak it just enough to fix this? So, reduce amount of swap :) This is because kernel needs some memory to manage swap too. Currently for amd64 this roughly reduces to the following rule (My apologies in advance for the extra simplification): 100MB RAM per 800MB swap space. So, with your current amount of RAM (893MB) it is recommended to setup no more than 7144 MB of swap. [1] [1] Let's look at vm/swap_pager.c:swapon_check_swzone(npages). Here npages is the total swap pages you want to setup. The warning will trigger if (npages maxpages / 2) becomes true. maxpages is the maximum pages the system can use for swap management. It is calculated as: maxpages = uma_zone_get_max(swap_zone) * SWAP_META_PAGES; By default SWAP_META_PAGES is 32 on amd64, and swap_zone limit calculates as available memory pages in system divided by two (assuming that maxswzone is zero (by default on amd64) and cannot further affect the limit). So that with X total pages in system, the maximum Y swap pages you are advised to have is: Y = X * SWAP_META_PAGES / 2 / 2, or X * 8 (on amd64). -- wbr, pluknet ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

Reporting a problem doesn't guarantee that it will be fixed (unfortunately) but not reporting a problem makes it extremely unlikely that it will be fixed. I feel recently freebsd is more focused on desktop's and as such developer's never develop for a heavy server usage scenario, This isn't intentionally true but it's true that few developers run large servers so they may not run into some issues that only impact large systems. Again, it's up to people who do run such systems to provide feedback about bottlenecks issues they hit so that they can be fixed. I keep coming across hardcoded low limits. As rightly pointed out default There are lots of defaults that were set some time (potentially decades) ago and may no longer be optimal. It's unrealistic to expect that all the defaults are correct in all circumstances and this is one area where end users can help by flagging defaults that they find need tuning. values now days are useless 128 for somaxconn? maybe ok for a desktop. But, as others have pointed out, this isn't one of them. Can you please provide more details on a use scenario where a listen(2) backlog exceeding 128 is reasonable. I cant tell app developers to fix their apps to work on FreeBSD, they dont care, if it works fine on windows and linux then the app isnt broken as far as they are concerned. FreeBSD is not Windows or Linux and never will be. There are lots of grey areas in the various standards that *BSD, Linux, Solaris, Windows etc comply with and some OSs interpret these grey areas differently to others (in some areas, it seems Linux has deliberately done things differently to other Unices for no obvious reason, and the GNU embrace-and-extend philosophy doesn't help). Writing portable code takes more than adding some .ac/.am files to an arbitrary blob of code and just because a developer thinks their app isn't broken doesn't make them right.

It wouldn't be the first time that I've seen FreeBSD expose some bug in some not-quite-right multi-threaded code because it doesn't behave like linux, regardless of what the specification says. :-) Adrian ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org
Re: [CFT]hwpmc update for sandybridge-e

Comments or concerns before I commit this? fabient@ already added some Ivy Bridge support to hwpmc. You may want to rebase based on his changes. I'd suggest SANDYBRIDGE_XEON, rather than SANDYBRIDGE_E only because I think it will make it more clear/correct. I'd also suggest putting something in uncore_pcpu_fini to not clear the EVSEL MSRs for SNB Xeon. By adding the new CPU type like you did, it has the effect of using the WSM EVSEL MSRs here (see the SELECTSEL macro in hwpmc_uncore.c). This is likely harmless, but isn't correct, and would be safer to just not clear the EVSEL MSRs at all, since there are no uncore events defined for your new CPU type anyways. Regards, -Jim http://people.freebsd.org/~sbruno/pmc_sandybridge.txt Sean p.s. I'm trying to hunt down some IvyBridge boxes to finish this off. ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to freebsd-current-unsubscr...@freebsd.org

If you have any objection, please raise it now. Initially I had problems with multi TB files (--unique, five to ten files) but I haven't had to do that in two(?) months. I will be getting back to that project in a month or so. It challanges a system's resources. :) And did it go much better with base GNU sort?
