(Oh, maybe a fraction of a second.) This was my top priority, and I was glad to nail it so completely. In 2.1, a large list of browser tabs doesn’t affect startup time. In 2.0 and 2.0.1, if you had a large list of browser tabs (in the hundreds), startup could take minutes, which is crazy. One thing I ended up having to do was rewrite almost completely the browser tabs manager. Shark is utterly and totally my good friend. (I find “Tree (Top-Down)” view most useful most of the time.) Want to know what the heck is happening? Run Shark while it’s happening. Then I used this super-cool tool from Apple called Shark. So what I did was identify a few places where people were reporting performance bugs the most. Okay, there was one silver bullet, sort of, here: just producing a Universal binary made it faster on Intel Macs. Sometimes there might be a silver bullet, sort of

Performance is a matter of reproducing the exact performance issues people run into, then making those specific things fast. And then, it’s slow only if you’re using multiple font sizes and have an embedded graphic. For instance, the hypothetical text editor is slow only with HTML editing but not when editing plain text. Or imagine an email app with a super-fast database-but the text editor can’t keep up with your typing.įact is, performance issues are specific-usually even more specific than the above. Imagine, for instance, a web browser with super-fast network but super-slow page layout.

I’ve talked a bit about syncing, so now I’ll talk about performance.Įxcept in the simplest or most specialized applications, there is no “silver bullet,” one place to optimize your code that makes everything faster. When I started work on NetNewsWire 2.1, I had two main things in mind: NewsGator syncing and performance.
