La Vita è Bella

I've started the Miao project one year ago, aim to build a smart pinyin input method for Mac. But I just got a new job 2 weeks after I started this project. This is quite a busy year, and I haven't really wrote much code for it.

A month ago Yong Sun from Sun begin to port SunPinyin to Mac, and now it's more than just works. I'm satisfied with the Mac port and use it everyday. As the Miao project is scratching my own itch, and I'm not itchy anymore, I should call it a day.

Sorry for anyone who waits for Miao, but I'm not going to reinvent the wheel.

On the Mac side, the initial backup takes me about 6 hours to backup 126GB data, by ethernet cable, so the speed is about 20GB/hr.

The writing speed via 802.11n wireless is as below:

fishy@Makelele:~/Video$ dd if=Pixar\ -\ Lifted.wmv of=/Volumes/Cacapa-1/foo.wmv
91582+1 records in
91582+1 records out
46890385 bytes transferred in 15.478993 secs (3029292 bytes/sec)

That's about 3MB/s. So I think the speed on Mac is acceptable, but it should be faster.

On the Linux side, I use Debian Lenny, with samba, afpfs-ng and a 100M ethernet cable (my Linux machine didn't come with a Gigabit ethernet port). The facts are:

Writing via AFP:

root@deBoer:~# dd if=prog03.mdb of=foo/foo.mdb
8736+0 records in
8736+0 records out
4472832 bytes (4.5 MB) copied, 6.89061 s, 649 kB/s

Writing via SMB:

root@deBoer:~# dd if=prog03.mdb of=/media/cacapa/bar.mdb
8736+0 records in
8736+0 records out
4472832 bytes (4.5 MB) copied, 6.57683 s, 680 kB/s

Reading via AFP:

root@deBoer:~# dd if=foo/bar.mdb of=bar.mdb
8736+0 records in
8736+0 records out
4472832 bytes (4.5 MB) copied, 8.87068 s, 504 kB/s

Reading via SMB:

root@deBoer:~# dd if=/media/cacapa/foo.mdb of=foo.mdb
8736+0 records in
8736+0 records out
4472832 bytes (4.5 MB) copied, 0.919922 s, 4.9 MB/s

So the conclusion is that, for writing, AFP and SMB are both slow. But for reading, SMB is much much faster than AFP, so you should use SMB to connect a Time Capsule on Linux.
