Openoffice and insane CPU usage?

post #1 of 3
Thread Starter 
Now I've encountered this on multiple computers, both here at home and in college. Sometimes processor usage on all cores jumps to 80% or even 90% when having two or more text files opened in Openoffice. It always happens on win7 64 bit for some unexplainable reason. Now honestly, why does writing a couple lines of text have to be a friggin troubleshooting nightmare? I'm used to Openoffice being slow, unresponsive, buggy pos, but really, insane CPU usage spikes now? All I want is to write a simple text file, sheesh.

Because it's written in Java and poorly optimized, that's why. Microsoft Office is written in C++, much better optimized (partly because they don't have to worry about it being cross-platform), and has lower memory footprint.

If all you want to do is write a "simple text file", you should use wordpad or notepad. Other operating systems also have really lightweight text editors.

Maybe power saving features are enabled so your CPU is actually running at around 800 mhz, for example, instead of the full speed.

I have Open Office installed on an ancient Dell Latitude C400 laptop with a 1.2 ghz Pentium 3 mobile CPU and 512 megs of PC133 RAM. Open Office runs fine on it.

EDIT - Open Office is written in C++ as well, with some minor uses of Java:

There goes Dopamin3's claim.
