Answer 1

1)) Use caching plugin i.e best example is WP- Supercache

2)) Minify all your css and JS files i.e remove the extra white spaces from CSS and JS files.

3)) Compress all your images i.e use a plugin http://wordpress.org/plugins/wp-smushit/ or smush.it

Answer 2

For better page speed and avoid these error you should try following things.

1. Enable Compression from Cpanel
2. You are using Wordpress so use any of the cache plugin.
3. Use header expiry using httaccess or page header.
4. minimize you scripts (css,js).
5. Use compressed images (jpegtran,pngout).

This will help you to improve page speed.
