"Oh hey Tobias, you said you made the mc directory listing fast. Look how slow the search on that site is ooooo"

Really?

I know that the search on that instance is slow. That's one of the several reasons why I/Dale actually want to upgrade the instance to the latest code base. If someone's inclined, we have that all tracked (https://github.com/krono/squeaksource3/issues/,  especially https://github.com/krono/squeaksource3/issues/64 and such)

The directory listing is fast. Like these ones:
	http://ss3.gemtalksystems.com/ss/STON/
	https://sdk.krestianstvo.org/sdk/croquet/

"dragster tech"? are you kidding? "extra complexity"? Its called divided responsibilities and industry best practices.

But you know what? Ask Levente to put map.squeak.org out there on port 80. See how fast it dies.

Best of luck.

The instance with the latest code base is btw: https://sdk.krestianstvo.org/sdk, ss3 at gemtalksystems is arguably the oldest one.

But still.

I have no part in this belly dance anymore.

Good day.
