You claimed it took a couple of hundred cycles to service an L2 miss. If a third level of cache is available, then it takes less than a hundred cycles to service an L2 miss. (I think the Xeon's L3 cache has a latency of 23 cycles. Is that correct?)
It's much more likely the size of the L2 cache is affecting you (i.e. your working set does not fit into P4's L2 cache but it does in Barton's).
Barton and Northwood have the same amount of L2 cache (512 KB). However, Barton's L1 data cache (64 KB) is indeed much larger than Northwood's (only 8 KB).

Several high-end x86 processors (e.g. the Xeon) sport an L3 cache;-)
According to Netgear, only RP614, RP614v2, DG814, MR814 and HR314 NETGEAR routers are affected. Patched firmware can be downloaded from Netgear's support website.

Nowadays, most of the spam I get comes through open proxies, not open relays. I think most mail transfer agents now come with relaying turned off by default, and the administrator must explicitly turn it on.
I don't know if Wirehub is representative, but in this RBL, open proxies clearly outnumber open relays.
FWIW, I follow the evolution of Mozilla's market share in Google Zeitgeist and they also show a pie chart of the different operating systems used to access Google.
Barton (Model 10) comes in three flavors: 3000+ (2.167 GHz), 2800+ (2.083 GHz) and 2500+ (1.83 GHz). All other things equal, the 3200+ should run at 2.25 GHz, same as the 2800+ Thoroughbred (Model 8).
However, if AMD were to increase the FSB speed, you can expect the CPU frequency to be slightly lower. I would guess between 2.083 and 2.167 Ghz.
Here is a complete chart summarizing the work done by the various Task Groups (a through m) and Study Groups. The results of the letter ballots are also available.
One of the major features of FreeBSD 5.1 will be further refinement of the re-worked SMP support introduced in FreeBSD 5.0. For specific information about the progress towards 5.1-RELEASE in this area, please see the SMP Project page.
Most spam is HTML-based, and not only does it phone home, but the dreck that it pulls in can be many times the size of the original message. I use the Mozilla mail client, and never open messages without first clicking on the handy connection icon in the lower right corner.

Q: What are the differences between the AMD Athlon 64 and AMD Opteron processors?
A: The upcoming AMD Opteron and AMD Athlon 64 processors are designed for different markets. For the server/workstation market, the AMD Opteron processor will undergo more stringent validation and reliability testing. Another difference will be in the number of HyperTransport links embedded on the chip. The AMD Athlon 64 processor will contain one HyperTransport link offering 6.4 GB/s data transfer while the AMD Opteron processor will offer three links. The processors will also contain different amounts of cache.
The first CDROM (and general net-wide) distribution was FreeBSD 1.0, released in December of 1993. This was based on the 4.3BSD-Lite (``Net/2'') tape from U.C. Berkeley, with many components also provided by 386BSD and the Free Software Foundation. It was a fairly reasonable success for a first offering, and we followed it with the highly successful FreeBSD 1.1 release in May of 1994.
Around this time, some rather unexpected storm clouds formed on the horizon as Novell and U.C. Berkeley settled their long-running lawsuit over the legal status of the Berkeley Net/2 tape. A condition of that settlement was U.C. Berkeley's concession that large parts of Net/2 were ``encumbered'' code and the property of Novell, who had in turn acquired it from AT&T some time previously. What Berkeley got in return was Novell's ``blessing'' that the 4.4BSD-Lite release, when it was finally released, would be declared unencumbered and all existing Net/2 users would be strongly encouraged to switch. This included FreeBSD, and the project was given until the end of July 1994 to stop shipping its own Net/2 based product. Under the terms of that agreement, the project was allowed one last release before the deadline, that release being FreeBSD 1.1.5.1.
FreeBSD then set about the arduous task of literally re-inventing itself from a completely new and rather incomplete set of 4.4BSD-Lite bits. The ``Lite'' releases were light in part because Berkeley's CSRG had removed large chunks of code required for actually constructing a bootable running system (due to various legal requirements) and the fact that the Intel port of 4.4 was highly incomplete. It took the project until November of 1994 to make this transition, at which point it released FreeBSD 2.0 to the net and on CDROM (in late December). Despite being still more than a little rough around the edges, the release was a significant success and was followed by the more robust and easier to install FreeBSD 2.0.5 release in June of 1995.

The Pentium 4 takes many cycles (over 7?) to do a simple left shift.
On the Intel NetBurst micro-architecture, SAL, SAR, SHL and SHR have a latency of 4 cycles and a throughput of 1 i.e. you could execute 4 SHL in 7 cycles if they had no data dependency (pipelined execution).

Only in criminal trials is reasonable doubt the standard of proof. In civil trials, a preponderance of the evidence is good enough (TM).
