Indeed. This does not change anything.

A DocBook document which size is 4Mb is already a VERY large one.

FYI, "Linux Device Drivers" by Alessandro Rubini, a ~500 pages book for 
which we have the DocBook source is just 2.2Mb large (and it opens in 
XXE v10 in about 2 seconds with the stock image and spelling options 
--see below-- and the stock memory settings).

It sure is.

1) If your DocBook document starts with a <!DOCTYPE> (e.g. <!DOCTYPE 
book PUBLIC "-//OASIS//DTD DocBook XML V4.2//EN" 
"http://www.oasis-open.org/docbook/xml/4.2/docbookx.dtd">) make sure 
that it's one of the DTD found locally in XMLmind XML Editor distribution:

<XXE_install_dir>/addon/config/docbook/dtd/
     V4.1.2/  V4.2/  V4.3/  V4.4/  V4.5/


2) In case your documents contain a lot of images, select menu item 
"View|Display Images|as Thumbnails". See 
http://www.xmlmind.com/xmleditor/_distrib/doc/help/viewMenu.html


3) In case your document have a large number of spelling errors (e.g. no 
lang or xml:lang attribute set on the root element and the document is 
written in a language other than English.), check option "When a 
document is created or opened: Never activate the automatic spell 
checker" (menu item "Options|Preferences", "Tools|Spelling" section, 
http://www.xmlmind.com/xmleditor/_distrib/doc/help/toolsOptions.html#spellOptions)


4) Finally, try -Xmx2048m, -Xmx3072m, -Xmx4096m, etc.




No sure that this will work and XMLmind XML Editor v10 would probably 
have exactly the same difficulties at dealing with 4-40Mb documents.

Sorry but XMLmind XML Editor is not good at editing large, monolithic, 
document. We aim to make it good (and fluid/nice to use) at editing 
large, *modular*, documents.
