Are they using the intel compiler? Are they making their binaries more thread-friendly? Are they using cc flags that exploit the new cache/features/instructions? Are they running their OS's with at least basic tuning to contain interrupts and kernel activity to particular CPUs?

Because I've found that the new hardware (Nehalems, for example) will give you a heck of a speed boost if you're doing the above.
It's real easy to have the compatibility features mask performance, really you gotta look at it like a new platform.
Anyway, those comments smell like making excuses to me, they are not even remotely specific enough to be defensible.
These stories are kind of silly. Investment banks deploy linux by the tens of thousands. That seems to have already indicated that linux is in the enterprise.
Corporate datacenters are now filling up with half-full racks because cooling & power requirements are through the roof. You end up being unable to increase compute resources because you have to put in fewer of the faster systems, gaining you nothing.
So hey, if you're listening harware vendors, see if you can't simply make the dang things run cooler on less power before you speed them up!
had to clonk my noodle a bit to get some older boxen patched conservatively. I grabbed the source for 8.11.6, created./devtools/Site/site.config.m4, then added

Visual pinball is an updated pinball construction set in many ways, you can either build your own or use it with pinmame to emulate/simulate old classic tables. It's VERY cool..
Yes, there is a feature in ip route 2 that lets you set up load balancing out multiple connections. It's a bit of a muddle to set up & make it work with IPTables but worth the effort. Setting cronjob to test if things are "up" is a little harder than it sounds though, a dying T1 line often is up 30% of the time, which is actually reason to leave it working for inbound email etc..
This software uses a linux kernel module that does some neat tricks with packet rewriting to do nat, inspect & modify DNS server replies, nat rules, etc. It also has a configurable connection monitoring service & a bunch of recommended deployments for HA email/web serving/outbound surfing, etc. Works on Solaris and Win2k too..
Runs on linux, does other rather clever things (can rewrite DNS replies as well for *inbound* load balancing). It works nicely with either a commercial firewall (checkpoint/raptor) or IPTables; or can be used just as an HA router
in front of existing firewalls. A feature this crowd will like- you can do everything via a command-line interface if you don't like GUIs too!
Traffic shaping. Set the max bandwidth ptp programs can get to a very low amount simply in the name of "traffic prioritization". Much easier to make the argument that email/web site views are higher priority, sigh that you are suffering along with the others.
There were 2 vynil releases that are also different from the radio series CDs & tapes, some added, more deleted material. I have these lurking around my parents house somewhere, I really should hunt them down and put them on ebay:)
There was a books on tape release read by the Radio voice of Marvin the Paranoid Android as well, that *also* differs from the books/radio.
Don't get me started on the original UK releases vs the US releases vs the later UK releases etc. "Most gratuitous use of the word Belguim" was orignally "most gratuitous use of the word F***" etc etc etc. I wonder if anyone ever showed DNA how CVS works:)
The original radio scripts book is my favorite of the hitchhiker's series, and Douglas's _Last Chance to See_ is my favorite book. I love reading the introspections of clever people with a sense of humor. Michael Crichton's _Travels_ is in the same league.
Douglas Adams has been one of my favorite authors for some time. I went to several book readings/signings, and I also have to say that he was sharp as a tack, extremely gracious, and had an easy-going sense of humor even with Rabid fans.

There are usually glibc-XXX-compat.i386.rpm files that you can install alongside of the newer ones for backwards compatibility. They don't seem to get installed by any of the options unless you go in and pick individual packages or just do it post-install though. hunt in your various rpm dirs for *compat*, can be quite helpful!
I mamed a japanese Jamma cabinet, it was only time-consuming, not difficult.

I'm browsing on a completely silent heatpipe 6600 (6645 OEM from Gigabyte to lidl, a Eurpoean bundler).
What can I say? It's silent. Completely. All I hear is the Disk seek.
These are very easy to find (google|froogle GeForce 6600)...
IBM has mentioned that they are working on water cooling.. a solution described to me as "a large radiator that replaces the back door of the rack".
I thought... eeeek!
it's "champing" at the bit for f@#$'s sake.

Boy, sendmail sure has a lot of documentation. As far as "giving the user enough rope to hang themselves" is concerned, sendmail is a rope factory !
