Coordination suggestion:

Note — I am assuming that the high-traffic situation is still a problem since a good deal of the new content is being posted at the mirror site. With that in mind:

May I suggest that during this period of high traffic, all new content be posted at the mirror site and that a prominent notice be placed at the top of this site that directs visitors to the new site to read the new content.

Just a suggestion.

Jeff M:

is a map of CA, realclimate and Watts for the last year.

But now Rush Limbaugh and Glenn Beck are mentioning Steve. That’s going to go on for a while and cause wild swings in traffic. Oh, and various attacks
of course.

I like the addin you referenced, but it wouldn’t help this site. Caching pages would, though. But it’s still not sufficient to handle 100 or 1000:1 traffic swings, that requires either homebrew directing traffic to separate boxes as I described in previous email or server farm doing so automatically.

And replacing php pages with static html, and reducing the complexity and length of php burden on rendering a post.

Climateaudit is largely text based, where there are images they are simple jpegs such as are embedded into posts or comments. There are no issues such as media file uploading or downloading which slows it down.

There are large, long page renderings by the php server. On CA these can be 1500 posts. That’s a big job. For one example, “Mike’s Nature…” thread is now 300 comments +. It appears as one long page when clicked.

This can be fixed by Dashboard, Settings, Discussion, Other Comment Settings, then check “Break comments into sections” and pick a number like 50. I personally like the 1500 comment method, but that requires a correspondingly higher CPU workload for that one mouseclick.

If a page averages 300 and this is set to 50, then server load goes down for page retrievals by a factor of 300/50 = 6, which is substantial.

Cheers.

Steve,

I think you could get away with some simple optimizations, this one may have a lot of bang for the buck:

Moving static image files off of this server will also help, I assume your server spends more time sending image data than it does rendering page content, however if it is spending more time rendering page content, a caching proxy server would be the next step, especially for the home page content.

Here is the first written word I've seen from Lord Monckton since the leak: They Are Criminals. Also, Lord Lawson announced the formation of Global Warming Policy Foundation (GWPF) in the House of Lords.

Steve,
In order to reduce the load being placed on your site at this crucial time, the best solution (for WordPress) is WP-Cache.

Hi Steve,

Keep up the fantastic work! Open Science with Auditing is the wave of the Future of Science.

WordPress allows you to have your own domain name used for any web site you host there. You should be able to set up a third level sub domain name under your own domain “_____.ClimateAudit.org” where you could have for example “mirror.climateaudit.org” or even just “www2.climateaudit.org”. This way you can keep your “climate audit identity” while moving to faster servers.

Just a thought.

All the best,

pwl

Denial Of Service (DOS) attacks as a cause of slow response time? Just a thought.

Reading and listening to the rationalizations of climate scientists about the current controvery, I thought of Talleyrand’s observation about the French ancien regieme ” They have learned nothing and they have forgotten nothing”. Looking up Telleyrand, I found an even more apt quotation “”Tout ce qui est exagéré est insignifiant.”: (“All that is exaggerated is insignificant.”)” . Climate scientists would do well with a deep study of Talleyrand.
