wrap-session taking close to 15s to process response? about ring HOT 6 CLOSED

It's hard to tell without more information, but my best guess is that you're running out of entropy for your random number generator. Does the problem persist if you switch to the memory-store?

I was unable to reproduce the issue with the default memory story.

That very strongly indicates that you're running out of entropy in your system, then. When it runs out, the process blocks until it can gather enough entropy to securely encrypt the cookie.

Sounds good, nothing you can do about then. Do you have any recommendations for what I could look into to potentially avoid bumping into this or improve the situation?

from ring.

It really depends on your operating system. My experience with production systems is that the amount of network I/O provides sufficient entropy that this isn't an issue, but YMMV.

It's also possible that the cookie middleware might be using more entropy than it needs, but if so, I'm not smart enough to spot it in the code. :)

Great, thanks for the explanation. Appreciate you looking into this.
