High CPU Usage
-
WordPress: Version 4.1.1
NextGEN: Version 2.0.79I apologize if this has been addressed recently — I searched the forums and found lots of commentary from around four years ago, but nothing too recent.
My hosting company (LunarPages – it’s a shared environment) has told me that over the last several weeks that my CPU usage is spiking. It appears that a lot of the CPU strain may be coming from NextGEN Gallery.
My traffic isn’t unusually high. It was even higher last year. For the month of March 2015, I have averaged 53 sessions a day and 1,073 page views a day. There haven’t been too many spikes in page views — they’ve ranged from a low of 317 page views to a high of 2,261. This is pretty consistent with my traffic over the last several months.
My site uses NextGEN Gallery extensively. I have a total of 363 posts and 344 of them use a NextGEN Gallery. I have a total of 25,936 images, so each gallery is averaging 75 photos. Even the larger galleries are generally below 200 images (although a few of them are around 350 images). I resize all of my images before I upload them to be 850 x 600.
Is there anything I can do to improve performance? I saw mentions in other much older threads about enabling caching, but I wasn’t able to see anything about that in the settings. Or is there a third party plugin that you recommend?
I am totally willing to upgrade to NextGEN Plus if you think that will help. I don’t think I need NextGEN Pro because I am not looking for e-commerce capabilities.
Here are some sample CPU stats my hosting company has provided.
