Rico Mariani's Performance Tidbits : Performance Quiz #1 (of a series?)


Recently there was a discussion on one of our internal email aliases in which this problem came up. I though it was an interesting problem so I posed this Quiz to assorted people I work with to see what kinds of things they would say.

Considering these three options:

Option 1:

sw.WriteLine(subject + ": " + message);

Option 2:

sw.WriteLine("{0}: {1}", subject, message);

Option 3:

sw.Write(": ");

Answer these questions:

Q1. Which of these choices offers the best performance?
Q2: Can you characterize the memory usage of each of these?
Q3: Which would the performance team generally recommend, and why?
Q4: What special factors might alter this recommendation?
Q5: What did you have do assume about "sw" to answer the question?

Creating ISO images with Nero 5.5 Express

Mark Michaelis' Weblog - August, 2003: "Creating ISO images with Nero 5.5 Express

I recently set up an old computer for my son, Benjamin, as he keeps messing up my wifes desktop and then I have to figure out how to get it back to the way she wants it. Anyway, as part of doing this I didn't want my son putting CDs in and out of the computer as he tends to scratch them. Instead, I decided to create ISO images of them and have him use them directly from the computer using Daemon-Tools. The problem, was how to create ISO images? I had a copy of Nero Express 5.5 but it took me some time to figure out exactly how to get it to make ISO images. (If you happen to have the full version of Nero you can find instructions for creating ISO images here.)

Here are the steps for Nero Express 5.5:

1. Launch Nero Express 5.5 (yes there is a 6 version out there but I don't have it.)
2. Select the Copy Entire Disk option.
3. Click the More>> button.
4. Click the Configure…
