<div dir="ltr"><br><div>In Ubuntu 12.04 with the MTP backport installed, when copying files to the phone, the speed is usually 1–2 MB/s, except when copying image files, such as jpeg and png. When copying image files the speed is usually somewhere around 10 kB/s=very, very very very, very very slow. Or even slower.</div>
<div><br></div><div>Why is that?</div><div><br></div><div>I tried to copy 1461 different image files and it took forever, so I interrupted it, erased all the files that had been copied so far, then in Ubuntu I zipped all of them. When copying the zip file, the speed was 1–2 MB/s again, and finally I extracted the images from the zip. All together a couple of hundred times faster than copying all the files unzipped, and the zip wasn't much smaller than the total size of the individual image files.</div>
<div><br></div><div>So that's my workaround for now, anyway.</div><div><br></div><div>But again, why does it take so long to copy image files?</div><div><br></div><div>I copied from the gnome terminal in all cases, using gcp (like cp but with a progress bar and not as many options as cp – I think it's in the repositories).</div>
