Textmining Memory Performance
Hi Ryan,
When I tested the application with large documents, Application
is raising java.lang.OutOfMemoryError. When I analyse your
source code, I have identified that you are using StringBuffer.
Performance wise using of StringBuffer is worth ful but
considering memory issue I think this is a serious issue.
Why because When I had done a test run on StringBuffer memory
Performance, after reaching the size to 13786405 bytes, JVM
raised an exception though i have lot of free physical memory
because I am using 256 MB RAM .I think this RAM is enough to
parse the 15 MB document but it is not doing that. Any ideas to
improve the performance of application in this scenario.
Thanks,
sudhakar

Send me your document, there may be some other problem. I don't think the
StringBuffer would cause that because text doesn't require that much memory
(3MB of text == about 5 books).
