I just checked it out, and it seems to work fine. Going back to nodes that I have just been to indeed loads from a cache (and it's not my browser) instead of perlmonks. Now if only you could setup a cron script to do the updating automatically, but we all know that is a foolish idea and shouldn't be considered (updating all the nodes in the cache every few minutes? lol).
One thing I will mention: merlyn has written an article that could be very useful in this sort of application. The only change you would really need to incorporate is this: set a lower time limit of when content should be re-grabbed from the perlmonks server, but where the older content is still shown. (ie: After a cached node is older than 3 minutes, show this 3-minute-old node and fork() off a process to recache the node in the background). Then, select a second, longer time limit at which content will be grabbed fresh from the perlmonks server and displayed directly to the user and cached. In this way, you will pick up a little more speed. For a more in-depth description of what I'm talking about, read that article I pointed to.
Update: Though it's cool, does this really have a lot of use? The only thing this really does is not have to hit the server for the same node every 2 minutes. Unless lots of users started using this, it won't decrease the server load on perlmonks in any way. Even then, you simply throw the user onto the actual perlmonks site as soon as they try to submit a form. Maybe if you could send form data through your server as well. All I do around here is submit forms: login, chatterbox (unusual, but it happens), consideration of nodes, search, poll, etc etc. So it doesn't give me all that big of an advantage.
If the above content is missing any vital points or you feel that any of the information is misleading, incorrect or irrelevant, please feel free to downvote the post. At the same time, reply to this node or /msg me to tell me what is wrong with the post, so that I may update the node to the best of my ability. If you do not inform me as to why the post deserved a downvote, your vote does not have any significance and will be disregarded.

On your update:
You said it right. If a lot of people who only browse perlmonks.org started using this mirror/proxy, it would help.
It not only helps perlmonks.org but also helps them since the response time is less = better.

Additions:
The mirror is hosted in Amsterdam, THe Netherlands (might only be fast in Europe)
The ads are shown just like on the original site and i hope that if you click 'm they are counted as perlmonks.org clicks
I hope there's no copyright problem or anything. If there is, i'll stop it immediately.
I am curious whether people would really want to use this mirror or why they would not. | [reply] |

That's just a proxy, not a mirror, isn't it?

Ehh.. you may have a point (although i don't know the real difference between them). It does look a lot like a proxy though.

Interesting idea. It has the benefit of possibly improving performance without touching the code or asking for more from the ISP.
On the downside, don't pages differ dramatically on a PER-USER basis? Level matters, user preferences matter, etc. This would seem to eliminate many of the performance benefits, or worse--produce incorrect results.

You are never logged in. The proxy is an anonymous user.

There is some strange behaviour in Internet Explorer now that i haven't figured out yet:
It renders the top of the page, then waits a while, and then the rest.
This would be consistent with the fact that the page is one big table which is always rendered when the </table> is found, but Mozilla renders it much faster.
The proxy is written in Perl by the way and if anyone is interested i could post the source here. | [reply] |

Laggy rendering appears to only be apparant in IE, Netscape loads just fine.
Is logging in supposed to be available in the mirror yet? It did not work for me when I tried, and I assumed that it was not accessable yet.
