One point in the question was the USB drive's filesystem.
Typically one would see FAT (aka pcfs for Solaris hosts) or NTFS here, of which NTFS support in the Unixes is often done with an userspace FUSE driver layer which tends to be slow even with the faster devices (i.e. HDDs). USB Flash is rather slow as it is (raw), and being USB over Ethernet does not help things much ;) Of course it is valid to see ext* or ufs or whatever on flashes, but the other options are typically less portable and rarely used. Also, the "pcfs" in Solaris was historically also known to be sub-performant, so AFAIK both Solaris 11 and illumos had projects to rewrite it with a modern FAT supporting driver. But with your OL hosts this part does not matter. I'd expect this to be a problem with NTFS/FUSE, primarily. See if "iostat" and similar server-side tools yield anything interesting regarding the disk traffic while it is being mounted? As a second option, it might be some networking speed mismatch resulting in pathological bandwidths, though this would be also visible with interactive (graphics) part of your sessions, probably. For example, some gigabit switches for servers with poor buffering settings or implementations were known to cause problems when the downstream 10/100M DTUs were used, google for details if this rings a bell for your setup.

Hi Alejandro! I've indeed checked the log and it seems pretty normal apart of the speed issue. The device is detected a few seconds after plugging it in, but seems to be completely mounted about 40 seconds later (after which the nautilus navigator with the mounted drive is automatically shown). I think this will be a storage capacity problem, as if I plug in any 1-2 Gb USB drive it gets mounted a few seconds after. I've also tried plugging several >= 8 Gb USB drives and it happens with all of them, so I guess it's "normal", but I'd still like to know whether there's a way to enhace the speed of mounting. I'm using Oracle Linux 6.3 and SRS 5.4 here.
