Re: 7520 Chipset support in 4.x
Many of the new MBs from such tiny vendors as Dell and Supermicro are based on the 7520, and word is that FreeBSD 4.x doesn't support it. Is support forthcoming? We have 2 Dell PowerEdge 1850 servers which have the e7520 chipset. They hang consistently in 4.10-RELEASE and below whenever there is high network or disk utilization. We have not been able to get any debugging info. After upgrading to 4.10-STABLE a couple of weeks ago, they no longer hang, but they are _really_ slow to perform network and disk operations. They work fine in FreeBSD 5.3, but unfortunately our applications do not run without recompiling. We do not want to change our environment to support different binaries for different machines, and we don't want to use 5.X in production until it is STABLE. I want to echo the above question. Are there patches available or forthcoming to fix the problems with the e7520? Thanks, - Rob Watt I think that we can imply from the lack of response on this subject that 4.x is not really still supported, since just about all of the new motherboards for Intel processors from leaders Dell and Supermicro are based on the 7520. So, ironically, in order to use the newer, faster processors with FreeBSD, you have to use the newer, slower version of the O/S.

So, ironically, in order to use the newer, faster processors with FreeBSD, you have to use the newer, slower version of the O/S. Yikes! Considering 4.x kept getting tweaked all the way to 4.10 where 4.10 is benched even faster than 4.9 in my experiences with the OS, I find it reasonable to assume that new code that hasn't fully matured and been fully adopted by mass may be slower. As in your previous post on the subject, I find it no where near as slow as you have stated. For one who couldn't figure out how to compile without the witness options and various other debug stuff into the kernel and base system, it prolly would be slower. After I took this stuff out of the build my benches were greatly improved, but alas, not to 4.10 speeds. Given time and mass acceptance of the OS which will adopt more coders and patches from people not yet using the OS I would expect it to speed up even more. When you do such a radical swing in codebases and haven't fully tested them, you should expect it. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

After I took this stuff out of the build my benches were greatly improved, but alas, not to 4.10 speeds. The POINT is not how much slower 5.3 is than 4.10 is, its the fact that a MAJOR chipset isnt well supported in what is SUPPOSED to be the mainstream, stable release. I know its difficult for you to stay on point, but at least try to get the point before ranting about the subject. Since you just babble about your tests but have never shown any results, no one really knows what your tests test, if anything. The only test anyone has posted was completely bogus (some nonsense about firing packets through a socket interface), so you just can't say my tests show unless you clarify what you have done. When 5.3 is released we can banter about benchmarks, as it seems pointless to do it now since its not done. It may be pointless anyway, since they've pretty much admitted that 5.3 isn't (yet) going to rival the efficiency of 4.x. I can accept that, but if 5.x isnt ready, then important chipsets should be supported in 4.x BEFORE they are supported in 5, not when someone gets around to backporting it. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
