One and all have heard me gripe about linux's crap performance.

One and all have also heard me go on about how Windows performs better
with less or no swapfile....

Behold, I imagine not!

Hi Ky!

Possibly - I don't know. Quite frankly I didn't understand, and that
probably because I don't know enough of the basics. Also noted the
article was written in 2004, which means it may have been accurate ten
years ago but not now, though I won't say just because something is ten
years old doesn't mean it isn't accurate now.

The only system I have running Linux is the Mythbuntu one, and have read
where one doesn't want to use Swap unless necessary because it is
mechanical; much better to use RAM as is electronic. Thigns are
configured to use RAM and then when that runs out to use the Swap file.
The 'problem' seems to be a cost vs. usage thing: on occasion do run out
of RAM, but may not be worth the cost of installing additional RAM (not
to mention the motherboard has to be able to accept it). I did read
recently where with sufficient RAM the Mythbuntu Backend machine would be
able to transcode on-the-fly, effectively allowing the viewer to watch slightly delayed Live TV and skip over the commercials, rather than
waiting for the Job Queue function to catch up. For me not that much of
a big deal to tap the Fast Forward key to zip through the commercials as opposed to the Z key to skip through (not see at all).

I'm thinking a compromise between the amount of RAM installed and usage
of the Swap File. I agree more RAM is generally better, but there is a
point of diminishing return.

If anything, it's probably a good deal more accurate now, given that high-memory boxes have become the norm. Why swap to a slow disk at all
when you've got plenty of RAM? Isn't the RAM there to USE??

Also, consider the SSD, which has a limited number of write/delete
cycles available before a sector dies. Swapping is basically constant write/delete. Probably not a good idea to combine the two.

Well, I'll have to admit the logic seems correct. If the RAM is there
should be able to use it, and it certainly is a lot faster than a
mechanical hard drive. LIS (I think it was here) with the Mythbuntu
system the more memory the better (up to the point of economics!), so as
to use less of the Swap File on the hard drive.

Also, consider the SSD, which has a limited number of
write/delete cycles available before a sector dies. Swapping is

Probably not. As my experience with Swap Drives is limited to
Mythbuntu, if one wanted to use a SSD then probably only for the remote Frontend, as the Frontend is for playback, wheras the Backend does the 'figuring' of what shows to record, on which tuner, commercial flagging, post-processing, etc., etc. IMO the backend is where not to skimp.
