But I can see that all the background stuff is using less than one core. That is not an excuse for bad foreground performance.

The stuff that used to be slow involved hard drive access, but today even when programs don't need to touch the disk they often manage to rack up significant delays. Not to mention how SSDs have 100x less latency than hard drives.

And if unicode support is causing serious delays when I'm only using one block of simple-rendering characters, then the library was designed badly.
