With little fanfare and positively no hoopla, Your JoeDog released siege-3.1.0 to an unsuspecting world. This release is better able to handle concurrencies greater than 1024 — please don’t use concurrencies greater than 256 unless you know what you’re doing. Siege is able to accomplish this feat through a combination of select on its first 1024 socket descriptors and poll on each one after that. Again, please don’t use concurrencies greater than 256 unless you know what you’re doing.

Hat tips to Abhishek Bhuyan, cheshirecatalyst, Teoh Han Hui, scooby, webus and Dave Fink for input and testing leading up to this release. We still have more work to do this area but we’re in a better place.

Hey ho — that’s not all! Three-one-oh comes with a new feature. We applied a patch from Eric Abbott which provides improved delay granularity. You are no longer confined to the rigid world of integers, one, two, three, four, etc. You can now use decimal precision like this: –delay=0.05 or this: -d 1.5  But here’s the thing about this feature: It’s kind of embarrassing that we’re adding it in the sixteenth year of the project but you guys never asked for it!

One more thing: please don’t use concurrencies greater than 256 unless you know what you’re doing. If you lay siege to apache with an out of-the-box config, it will not be able to handle the load and all you’ll do is make a mess.
