Memcached vs varnish for wordpress?
Currently i'm using memcached with a old wp plugin to run full page cache on a high traffic site but this plugin don't cache my widgets so i had to use another plugin to avoid mysql usage as much.
So i found another site -competitor- using varnish cache (reading his request flags) this is better caching system than memcached?.
I read is cool use both but i'm running out of ram so beetween one or other wich is better to use?
Site is like a videotube but all videos are embedded from external sources, but database had a lot of entries.
