Hi Mathieu, It may well be an unfortunate interaction with Nautilus. But the image thumbnails are not the issue: I tried it on a single folder, that contained a single folder. No thumbnail. Even if there were, it wouldn't explain this effect.
For comparison, I used Nautilus to navigate my hard disk file system. It's not exactly fast on this netbook, but directories with say 60 items or so (many items with thumnails) open in 2-3 seconds. As opposed to 2-3 *minutes* using OBEX. So * OBEX itself is pretty fast * Nautilus is ... not *that* slow * OBEX + Nautilus is *unusably* slow. It was not this bad in Ubuntu 10.10. Somebody isn't talking to somebody else right. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to nautilus in Ubuntu. https://bugs.launchpad.net/bugs/1004601 Title: OBEX file browsing extremely slow Status in “nautilus” package in Ubuntu: Incomplete Bug description: With recent updates to Ubuntu 12.04, OBEX file browsing of Bluetooth devices is working again, but still not quite as well as it was in the 10.x series. This is a Samsung NC-20 working with a Nokia C5. In particular, OBEX file browsing is extremely slow, at least using Nautilus. It was never exactly snappy, but it was nowhere near this slow in Ubuntu 10.10. From the Gnome bluetooth-applet, click the item corresponding to my phone, and pull down "Browse Files..." . An icon for the phone promptly appears on the desktop. But after this, things grind to a halt. It typically takes a couple of minutes to open a directory, even a directory containing a single directory item. 100% reproducible on this system. Other Bluetooth functions are quite fast. For instance, I browse the web over BT DUN connections, and it feels like a fast modem. Please have a look at this! We're almost there!
