Subject RE: 96 M memory for JVM still not enough, what can I do?
Date Thu, 24 Aug 2000 20:15:58 GMT
I managed to find a NT to run it, and from the taskmanager, I see the memory
usage is about 214M.

	 there IS outofmemory exception in some cases, but sometimes it just
hangs.
	Regarding my xml/xsl. Since in my test files, I started from a 10k
small
	xml, which is very simple. Then I copied one line <a>something</a>,
pasted
	it hundreds of times. I tried several times when the file grows to
100k,
	200k, 400k....    It is already very slow at 600k, but still shows
up.
	However, when the size increased to 800k, I waited 20 minutes and
still
	nothing happens.
	My desktop has 128M memory, and I allocated 96M to JVM. No swapping
happened
	in this case.
	I also tried to increase JVM memory to even more, but then the
computer
	keeps thrashing&paging........mine is windows98, I do not know where
task
	manager is.
	Thank you so much.

		If it never runs out of memory, and doesn't excessively
swap, then
		I am not sure that it's a memory issue. What is the CPU
activity
		meter doing (can you run top or task manager, depending on
		your OS?)

		Is it possible that something in your XML/XSL/XFO causes an
		infinite loop? Are you sure it's the size of the file that's
to
	blame?
