One other thing: I've checked the support archives but did not happen to
see any discussion of what I've run into. As I think you know, we've
been using XXE 5.3 and when I made the changes needed for XXE 7.2, I did
a timing test on a large PPP document (255 pages with a lot of
what we call interlinear examples).
Frankly, I was expecting XXE 7.2 to load and run faster since I
understood it used Java 8 and I had heard that Java 8 was faster than
Java 6.
It's not a Java problem. It's an XXE problem. XXE 7.2 is substantially
more complex that XXE 5.3, hence potentially slower.
I tested this on my Windows computer with no other applications overtly
running. Here are the (surprising to me, anyway) results:
XXE 5.3 took about 5:00 minutes to load.
XXE 7.2 took about 13:30 minutes to load.
On my (fast) Linux box, it took me ~4 minutes to load "JJJ.xml", which
is insufferable.
Does this correspond with what you might expect?
No. 255 pages is not a big deal. A CSS-styled, large, monolitic, 2Mb,
500 pages, DocBook 5 document takes just ~5 *seconds* to open on my
Linux box.
Could I be doing
something in the CSS file that is this much slower with XXE 7.3 than
with XXE 5.3?
Indeed. Your CSS file is 10,000+ lines long and is full of form controls:
---
content:text-field(attribute,label)
---
and dynamic CSS evaluations:
---
display:concatenate(xpath("if(not(...)"));
---
This is quite uncommon.
Compare this to the DocBook 5 CSS stylesheet which does not prevent a
500-page document from being opened very quickly.
Could the automatic spelling checking be a factor?
No. With the automatic spelling but no CSS, it took me ~1 *second* to
load "JJJ.xml"
The PPP document (as a zip file) is available at
https://XXX/YYY
We'll look into this, try to improve the situation this and get back to
you. However this may take a few weeks. (This will be treated as a bug
we'll try to fix for XXE v7.4.)
