Safari almost has no extensions, and is severely lagging on a workstation-grade Mac and I suspect it's the huge amount of bookmarks that I have.

Furthermore, invoking the list of tabs (actually a grid of tabs) is also very slow and feels like the machine is struggling doing it.

I like Safari. It's extremely lightweight. But it's not given proper attention by Apple, which is a big shame. They have the resources to make it as fast as Chrome is. But they don't. :(
