Title: 90% Disk I/O on a high traffic website
Post by: nuffsaid on April 16, 2017, 10:39:47 PM

Hi

i have a high traffic website hosted on my server every time the user number goes above 1000 the server hits a 90% Disk I/O for a while

Can anyone recommend something i can do to lessen the load?

I have a server with 16GB Ram,  8 x 2.5GHz cores and a 2tb HDD

this would need to be checked on your server, but you can try to enable nginx and varnish for start (if you are not using some kind of shopping site)

My first reply to any "High I/O disk usage" is to instantly switch from HDD to SSD! You'll see both your IO and Cpu load go DOWN. No joke. You can run a web server that gets 10,000s of hits daily with a small 120GB SSD with your current setup and never go above 2.00 CPU average load.  8)  ;D

Yes, you should switch to SSD first and then optimize web servers so that your server will handle some more traffic. :)
