Would DEVICE_POLLING and/or jumbo frames likely methods for enhanced speeds? Firstly we've been discussing how bad and inefficient the broadcom controllers are. If you have a tyan MB with onboard controllers they are incredibly slow (ie inefficient), as well as being quirky. If you have a PCI-X slot put in an intel card. They have built-in interrupt moderation so you don't have dick around with polling. A 133Mhz intel controller (make sure they have the GB chips on them and not the EB) will use half the cpu of the on-board broadcoms. If you don't believe try it with one box and measure the cpu usage before and after. Its worth the $50. investment in the card, believe me. I'll look into the Intel cards, but unfortunately I'm probably stuck with the onboard broadcom devices for the immediate future. There is one expansion slot (whether its PCI-X, I don't know). I was actually planning to use the slot for infiniband, myrinet, or the 10 GiGE cards that Drew Gallatin has mentioned. While polling may marginally decrease the cpu load (depending on how bad FreeBSD 6.1 is on interrupt overhead), its also going to add latency to the processing of packets, which is the opposite of what you want to do. This is the conclusion that I reached in reading i386/conf/NOTES.

Though this seems like a hack, because when someone connects to the seem via the FQDN, /bin/hostname will give the wrong answer. Associating the ypdomain with the FQDN from the DNS is convenient, and a convention that many follow, but it is not required, by any means. The O'Reilly Managing NIS and NFS book is a fine reference on this sort of thing, BTW, and is probably available online in PDF form if you look. Thanks for the pointer. I'll go looking for this book. Nevertheless, YP/NIS predates many of the more convoluted network designs that people set up nowadays, and was intended for machines which have a single identity even if they have multiple NICs-- Sun used to assign the same MAC address to all NICs on one machine, to ensure that people respected collision domains. I don't see how this is convoluted. In fact, I would be inclined to claim that it is the defacto method for setting up an internal computational cluster s --- node1 internet -F- FQDN|master --- w --- node2 t --- node3 where swt = switch. It is not normally desirable to set up a YP/NIS master server on a machine which is multihomed in the sense of doing NAT or needing a firewall to separate internal from external, and obvious a firewall machine running zero or the minimal necessary services is a lot more secure Note that -F- actually has at least one firewall. Only people in the apl.washington.edu domain can get to FQDN. I was hoping to use NIS to simplify the propagation of info (eg., passwd, hosts, etc.) from master to the nodes. Propagating the info by hand isn't too bad because I only have five nodes represently. However, I hope to grow an additional 11 nodes. -- Steve ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Setting up NIS questions?
I have 2 NICS in the master node of a small cluster. bge0 is connected to the outside world with a FQDN and registered DNS IP address. bge1 is connected to a 192.168.0.x internal network. I'm trying to configure NIS for the internal network, but ypinit is grabbing the FQDN. I've read the Handbook and ypinit manual page without too much enlightment. :( What I'm after is 192.168.0.10 NIS master server 192.168.0.11 NIS slave server 192.168.0.[12-15] NIS clients Anyone have a pointer to a method to achieve my goals. -- Steve ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

This makes an enormous difference in boot up times. With vm.old_contigmalloc=1, fxp0 probes within a few seconds. Without it, fxp0 takes more than 7 minutes to probe. Some people are seeing slow boot/configuration with new style vm_page_alloc_contig/contigmalloc. yep. I am doing some profiling of vm_page_alloc_contig() and have found that larger physical memory configurations makes these problems much worse. yep. I have 12 GB.

Some of the changes will only occasionally save a few page checks, but others changes could save several hundred or more page checks on every call.

Setting up a danish locale
Problem: We have a visiting scientist from Denmark, whose laptop died a horrible death. A colleagued asked if I would loan him a currently unused system in my office. I've set up FreeBSD 5.3 on the system and everything appears to work except for setting up a Danish locale. Disclaimer: I searched the Handbook, used google, and spent a few hours reading up of login.conf, locale support, etc. But, we are stuck without the danish locale. I have setup a ~/,login_conf in the user home directory that contains dhcp-78-77:kargl[201] cat .login_conf me:\ :charset=ISO8859-1:\ :lang=da_DK.ISO8859-1: When we login, we see that the locale is set dhcp-78-77:kargl[202] locale LANG=da_DK.ISO8859-1 LC_CTYPE=da_DK.ISO8859-1 LC_COLLATE=da_DK.ISO8859-1 LC_TIME=da_DK.ISO8859-1 LC_NUMERIC=da_DK.ISO8859-1 LC_MONETARY=da_DK.ISO8859-1 LC_MESSAGES=da_DK.ISO8859-1 LC_ALL= But any attempt to enter a danish character in for examples xemacs fails. From my colleagues comment a Right-Alt / o should yield a lower case o with a slash through it. His system is running Xorg 6.7.0_9. I suspect that I need to change/update his xorg.conf file.

You may need that for the Danish characters to work right. intlfonts is not installed. I'll add those and update xorg.conf.
