Too early to ask, but if you guys had to guess will iOS 11 be very slow on iPhone 5s? (like lagging a lot) or it's as smooth as iOS 10?
 
well is seems to work ok. Maybe a little bit slower than 10.3.2.

I had some problems though. After the post-installation process the 5S was stuck in a loop and I had to hard reboot the device. In the mean time I was installing my MBP with MacOS 10.13b which required a second factor from my iPhone, which was stuck in that loop...

But somehow it revived again. and both work fine now.
 
I've always held the belief that an iOS device runs best with the iOS version it ships with. 5S runs best on iOS 7, 5 run best on iOS 6
 
it runs fairly smooth for a beta but i think that even the final release will be slower a little bit

It will likely be the opposite

This beta has signs of slowdown even on an iPhone 7

It's a developer beta, they've all been like this

5s is a competent device I expect it will run iOS 11 well in the end (at least as good as iOS 10 was on iPhone 5/c)

Considering how the 5s performs relative to A8 devices, I expect it should perform similarly if well optimized.

It seems (I have to verify it) that with low battery (<15 % red battery icon) the 5S becomes super slow. I had to (hard) restart it, and every time after first unlock of home screen the phone became unresponsive resulting in black screen with "hour glass" and finally rebooting in apple logo.

Whilst charging above 20% everything seems ok-ish again.
 
iOS 11 iS last update for both iPhone 5S/6. in my opinion both device are fckn slow
