Nginx Pagespeed Module: What is "Ngx_pagespeed Slow write operation on file /usr/share/nginx/ngx_pagespeed_cache..." in error logs and how to fix?

mx flag

I am running an Ubuntu 20.04 LEMP server with the pagespeed module for Nginx in a business environment. In my /var/log/nginx/error.log I am seeing the following error:

[ngx_pagespeed 1.15.0.0-8811] Slow write operation on file /usr/share/nginx/ngx_pagespeed_cache/v3/mcmo.is/https,3A/,2Fwww.mcmo.is/wp-content/uploads/2022/05/McMo-Art-Tryclops-1-scaled.webp,.tempqfKyZe: 61.512ms; configure SlowFileLatencyUs to change threshold

What exactly does this mean, and how can I improve/fix things so that this error no longer appears?

Questions on Server Fault must be about managing information technology systems in a business environment. Home and end-user computing questions may be asked on Super User, and questions about development, testing and development tools may be asked on Stack Overflow.

@RomeoNinov Its called "serverfault". I'm running a SERVER! I'm pretty sure this applies buddy. You don't know what you're talking about.

Here is the text you get when you create new question: To improve the chances of your question staying open and getting an answer, make sure that it is about **managing information technology systems in a business environment**. If your question concerns personal equipment, try asking on Super User instead.

@RomeoNinov I added "in a business environment" in my original post since this server is being run for business. Thanks for being rediculous man.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
