Like i said; it works like a charm; you do not need to worry about your sidebar; the trick with wp-super-cache is that you should not cache the files for a long period of time; most sites get slow because they get many visitors at the same time; i.e. those who read your rss feeds and click on a news item as soon they see it, generating a sudden rush to your site, if you made wp-cache to cache the site 15 minutes it would only keep the files cached for that time of period and show those users the same cached page, but if after 15 minutes new visitors would come by; they would see a new fresh page.

If the sidebar has external links it will always show you dynamic content; (i.e. advertisements and so on).

If you would have a plugin which is wp-cache aware but should NOT be cached you can enter these in the configuration to be excluded from the cache.

In other words; it will also work for you; and it will bring the load of your blog down quite a bit.

If you except a digg or slashdot effect to happen; you can enable a special option in wp-cache which also stops comments from being directly updated.

This would be the top1 plugin I would recommend anyone using wordpress, and find it strange at least that it is not included as default in wordpress as of yet. (all larger CMS systems have this feature).

Thanks for letting me know how WP-Cache works for you. I am going to test it here, and see if it makes any difference. My only concern is whether or not the sidebar will continue to update, since it is a dynamic part of the site. Any knowledge about this?

Due the fact that now not each post needs to be retrieved from the sql server (still have to watch out for plugins which are not wp-cache aware) things will load much faster; and if you post a new article you can setup wp-cache in such way that it will clean the cached page and shows your visitor always the latest posts.
