Categories: Pogoplug Mobile & Series 4
Hi...
I have a Pogoplug 4, with a 160GB SATA drive (formatted on a Mac) connected directly to the SATA port: "# mount" on the pogoplug reports:
/tmp/.cemnt/sda2 on /tmp/.cemnt/mnt_sda2 type ufsd (rw,nosuid,nodev,noexec,noatime,nls=utf8,uid=0,gid=0,fmask=22,dmask=22,nocase,force)
I copied a 1GB .m4v file from my Mac to the 'plug (just drag and drop using the finder window for the pogoplug drive). It took a few minutes to start the transfer, boogied at 20MB/s (160Mbps) for the transfer, and then took another few minutes to decide everything was OK. During the "preparing to copy" time ("the initial lag") and the "end lag," the Mac is receiving about 700KB/s of data from the Pogoplug. SSH'ing into the pogoplug and doing "ls -l" on the mount point shows the file isn't being created until after the initial lag. During the lag times, ps reports hbplug is consuming about 67% of a CPU, down from 95% when data is streaming in.
ps -axl | top during the end lag:
Mem: 117052K used, 1576K free, 0K shrd, 3736K buff, 81288K cached

What gives?
When I instead use the Pogoplug Uploader, the startup time is a few seconds ("parsing"), and I get the same speedy transfer (with no finish-up lag).
Thoroughly confused...
