[oXygen-user] XML Author: Chokes on Big Images?

[Andrew Welch]

Try giving it more memory: open the "oxygen.vmoptions" file (its in
the same place as the exe) and change

-Xmx700m

to

-Xmx2000m

Thats the amount of memory in megabytes that Java will take when you
start Oxygen... it will never go higher than that, so thats likely to
be the reason why you notice the slow down around 700 - 800mb.
