Eclipse - CDT Content Assist extremely slow

I just installed eclipse-cdt 3.2.2 on Linux (Mint). The content assist feature which pops up when you do a "." or "->" on a struct or struct pointer, is extremely slow and freezes the entire IDE for around 10-20 seconds.

Th开发者_开发百科is I feel, is because it searches through the entire include directory /usr/include that comes by default for any C project that you create.

How can this issue be solved?

Thanks..

You have bug 196203 which points to this page with some settings to perform.
It includes:

• how to make Eclipse actually use Sun's Java solving the "Eclipse is horribly slow" problem caused by bug 45347.
• raising the default heap size.
