It aims to do the same thing...serve big JP2s (and other images) over 
the web, so from that perspective, yes. But, beyond that, time will 
tell. One nice thing about coding against a well-thought-out spec is 
that are lots of implementations from which you can choose[1]--though as 
far as I know Loris is the only one that supports the IIIF syntax 
natively (maybe IIP?). We still have Djatoka floating around in a few 
places here, but, as many people have noted over the years, it takes a 
lot of shimming to scale it up, and, as far as I know, the project has 
more or less been abandoned.

I haven't done too much in the way of benchmarking, but to date don't 
have any reason to think Loris can't perform just as well. The demo I 
sent earlier is working against a very large jp2 with small tiles[1] 
which means a lot of rapid hits on the server, and between that, (a 
little bit of) JMeter and ab testing, and a fair bit of concurrent use 
from the c4l community this afternoon, I feel fairly confident about it 
being able to perform as well as Djatoka in a production environment.

By the way, you can page through some other images here:

Not much of an answer, I realize, but, as I said, time and usage will tell.
