serious issues with microSD/lanshare/PCManFM + image issues

[autumn]

DukeComposed, thanks for posting but I don't understand much about RAM. All I know so far is I've seen the article which says more ram equals worse performance, and these pesky issues illustrated above show that to be so (my poor panel has recovered, as I blitzed the job and just manually backed things up). I'm not very tech, but concerned about the permissions/slow issues I keep hitting, and PCManFM/lanshare in with that. I'm trying to get to why some things are so slow which weren't in mx21, plus concerned e.g. that I couldn't change the dirty settings without or with sudo. Have at least got a snapshot done and running the live was 100% fine, so that's something good.

Be precise. Profile, don't speculate. Post exact URLs to reference documents when you cite them.

Sorry to burst your bubble, but that's nonsense.
Just remember that any computer operation is only going to go as fast as the slowest part involved can process the data. For example, a USB 2 port has a maximum transfer rate of 480 megabits/sec while a USB 3 port has a maximum transfer rate of 5 gigabits/sec. So if a USB 3 capable drive is inserted into a USB 2 port, that USB 2 port is going to be the bottleneck.

I did. Please see post #5.

Best take that up with Opensuse, as that's where I saw it. Advice was to look up dirty settings, which I did, and that article came up at the top and seemed to clearly explain things. I don't know. Am not very tech. Just know there are significant issues with larger copies that didn't exist on mx21. Also issues with permissions, and this seems to affect PCManFM, lanshare, freefileshare, all kinds of things, and even since starting this thread I've found it not possible to change the dirty settings via sudo. There were none of these issues when running mx21, with the same setup (xfce/mate) and same programs installed, so I'm hoping to understand why and hope to find how to solve things.

I did. Please see post #5.

From your link: "Low performance may occur on a Linux NFS Client machine with a large amount of RAM, while writing large files to an NFS mount."

Are you running a SUSE? Are you writing to an NFS mount?

When someone is told to generally search, you read links that all tend to cover generally the same, so you can get a ghist. That's what I did. The Suse link was the clearest explanation of those I read, and, as I said, I wasn't sure, but am experiencing poor performance on the new machine/64ram, whereas the old machine/16ram, on mx21, performed great. So the Suse link seemed to explain the general concept and issue best, as far as I could tell. Again, I'm asking advice, and posted the link and my obvious questions more to try to get to the bottom of things.

First you criticise no link, because you didn't bother to read the thread. Now you criticise the posted link. It's very clear you're not here to assist with the issues, so I've reported and blocked.

I read your linked article and it really doesn't fit as a citation for your current problem:
-- It's specific to Suse Linux Enterprise Server
-- It makes no mention of the actual hardware involved
-- it infers, but doesn't categorically state, that Linux is Linux is Linux and it's not. A server environment is very different from the desktop environment that we offer with MX
-- it's out of date. SLES version 11 was released in 2010 and SLES version 15 went EOL in 2018. Linux is such a fast moving target that the seven year gap between SLES 15's EOL and now is equivalent to decades or centuries in other fields of study.

I checked the reported SUSE issue, too, and some of their other materials that link to that document number 7010287. I agree with what j2mcgreg says above. Adding to that, the reported "large amount of RAM" was even back then, in this context, more RAM than what you are dealing with, autumn. The document was linked to in the SLES 11/12 OS Tuning & Optimization Guide at www.suse.com a decade ago, and it contains clarification that even then the "large amount of RAM" meant 128 gigabytes and above. It's a specific issue, in a different context and use case, and with parameters that don't match at all with what you are dealing with.

I can only refer back to the obvious that I've already said ... no idea, not tech, trying to post and discuss things with a view to solutions, but all it turns into is deliberate criticising and no reference at all to the issues happening. I made the effort to look things up, yet am supposed to be some kind of tech einstein and know if what I'm reading is 100% right? Why would I be posting here if I was some kind of tech einstein?

Right now, after reading around more, I'm trying to install an antix version of the kernel, after seeing extreme slowness referred to in many places as a long-time kernel bug that crops up, and that seized up again for a while. I try to install a game, and it says it'll take 2 hours instead of the 10 minutes it used to. Permissions blocking this, that and the other, but apparently nobody who made mx23 has any idea what has changed. This is too much. Since there's no answer to clear issues, I'll try to seek somewhere Mate and sysV co-exist and receive support.
