Server Load High

I believe it was memcache that they used on the server.

I did have an rss feed on the homepage, using the plugin continuous rss scrolling. But no where else on the website.

Was it your own site’s RSS feed, though?

And if you have not yet, turn that off. And switch to the default Twenty Ten theme ??

Unfortunately, I can’t get accurate test loading by switching over the domain name. But I have been load testing using loadimpact.com. I have removed the RSS Feed in one of my tests and it still crashed at about 75 concurrent users.

I did notice that the table for wp_postmeta is almost at 6000 records. That sounds like alot?

No. Not really (Mine is at 3000). If you wanted to wipe out your revisions, it’d trim it down.

Server load is high generally because something’s causing too much ‘work.’ Yeah, I’m captain obvious there ?? If nothing, from trimming plugins to changing themes, works, then you have to sit and look at your server. Make sure PHP is installed in a way that works. Optimize your httpd.conf for WP. Master TOP. That kind of thing.

So I created a new wordpress site and left it with the TwentyTen theme, ran the same Load Test, and it crapped out at the same point, 60 clients or users. So this is now really confusing me about where to look, or even if this Load tester is even accurate.

or even if this Load tester is even accurate.

always a possibility. we all answered on the assumption this was a live server. ??

What’s the specs? How much RAM?

Which load tester are you using too? Is it public something we can share?

Cause I use WP multisite on a VPS that gets hammered and it’s only crashed when I’m dumb enough to upload very large pictures and publicize them without caching first ??

I’m using Loadimpact.com. I can

Server is 40 GB of Disk Space, 1024 RAM, with a load balancer so a duplicate server to share the load. Plus the DB’s are on their own server as well.

I can share the results, see below. Testing is on my rackspace server, and is the same website you would see if I switched over our main domain name to this IP.

1. Test with theme TwentyTen as if you set it up for the first time.

2. Test with no plugins, using my existing site seen here: https://50.56.52.252/

3. Test with all plugins installed, using my existing site here: https://50.56.52.252/

Interesting. I ran a couple tests on my boxes and the loadimpact tests seem to contradict my own monitors. How odd. (Loadimpact says my site will pop out at 20 users, but I’ve had a couple hundred at once and been okay). I’m going to poke around on this some more.

That is interesting. Let me know if you come across anything.

Thanks.

Weird. it says my beefy dedicated box running nginx will take 15s to serve 30 clients. And I know that’s not right.

See? That’s what I mean! Also, the bugger spiked my memory usage through the roof! I think it’s running a REALLY dirty check that isn’t right. I may appropriate my office tools and test it on a ‘random external site’.

Ah, still working away at this one. So next step after some testing is we are changing our server config on Rackspace from Ubuntu to Redhat.
