Plugins that can spike CPU

CPU times for the past hourI learned tonight that three plugins that I was running caused so much CPU usage that my hosting provider shut me down. So if you are using this, watch your CPU usage or the same might happen to you.

  1. Broken Link Checker – This makes sure that you don’t have any broken links. I had it running all the time. It was only 50% in accuracy. So if anyone has anything that works better I would love to know it.
  2. SEO auto links and related posts. This provided many links automatically from my past post history. It has the side effect of finding the same content, so it’s not the best in my opinion.
  3. SEO Friendly images. This automatically provides alt and title descriptions. This was the third most cpu intensive plugin.

So it looks like dynamic plug-ins can cause some serious issues.

Also I had been having a small increase in traffic lately and so reinstalled WP-Supercache plugin. I used the mod-rewrite feature which I haven’t used before, so perhaps this will make a difference.

Don’t have more than 20 plugins

Otherwise you may not only bring your WordPress account down, but you may also crash the server for everyone else. That is what I just did today.

I called in and the server administrator called me, and we discussed several plugins that can cause problems on shared servers. I disabled CommentLuv, YARP, and Broken Link Checker. While I was at it, I also disabled Google Analytics, Google Site Verifier and one other. He said that YARP was known to cause problems, and once I described what Broken Link Checker does said that might happen as well. He also suggested I not use VaultPress which he said also coincided with the high server usage that caused the crash.

I had never been told by other providers that this was a problem. I wonder now if WordPress could put out some guidance and tell people not to do shared hosting if they have more than 10 plugins.

WordPress Plugin Broken Link Checker works great-not so much Godaddy

I installed a new plugin today called Broken Link Checker. It is going through all my past posts and pointing out any that have broken links. Then I will update a few a day until I get them all fixed.

However the downside is that this has slowed down the site to a crawl. If you have Godaddy and want to use this plugin run it during your least traffic period. Today isn’t so bad that this is occurring.
