You blog is faster in comparison with mine! (grrr) have a look at Web Talk and let me know....
EDIT: your blog is NOT downloading faster than mine...I have tried other methods than the one suggested on the post above and my blog is faster...read below pls :)
However, here are my suggestions to have a fast blog:
Install xcache on your server.
enable gzip compression (or zlib)
Enable mod_deflate on your server. here is how:
<IfModule mod_deflate.c>
<FilesMatch "\.(js|css|html|htm|php|xml)$">
SetOutputFilter DEFLATE
</FilesMatch>
</IfModule>
cache locally. Here is how:
# Set up caching on media files for 1 year (forever?)
<FilesMatch "\.(flv|ico|pdf|avi|mov|ppt|doc|mp3|wmv|wav)$">
ExpiresDefault A29030400
Header append Cache-Control "public"
</FilesMatch>
# Set up caching on media files for 1 week
<FilesMatch "\.(gif|jpg|jpeg|png|swf)$">
ExpiresDefault A604800
Header append Cache-Control "public"
</FilesMatch>
# Set up 2 Hour caching on commonly updated files
<FilesMatch "\.(xml|txt|html|js|css)$">
ExpiresDefault A7200
Header append Cache-Control "proxy-revalidate"
</FilesMatch>
These are just few tricks but you should be fine ;)
