Eclipse IDE with PyDev too slow!

When Eclipse IDE is too slow while developing Python with PyDev,
and you've done already everything you could do (e.g. increase the -Xms, -Xmx, -XX:MaxPermSize, and change the -Dosgi.requiredJavaVersion to the latest etc...) and still is slow,

try turning down (not use) the Pylint and Code Analysis.

This might help...
