Subject: Re: Let's talk about the elephant in the room - the Linux kernel's inability to gracefully handle low memory pressure
Date: Tue, 6 Aug 2019 15:43:43 -0400 [thread overview]
Message-ID: <ed477e7f-e159-6bf7-efa9-5d82cea3da96@georgianit.com> (raw)
Sorry, I don't have the original message to reply to.. But to those
interested, I have found a solution to the kernel's complete inability
to allocate more memory when it needs to swap out.
Increase the /proc/sys/vm/watermark_scale_factor from the default 10 to 500
It will make a huge difference, especially with swap on SSD, the kernel
will swap out gracefully to allocate more memory, and you can get a few
GB more memory in use before really noticing performance problems.
