I'm just curious to know if some of the performance gains seen on the Linkstation Pro can be duplicated on the Linkstation HG, or if these improvements are due to hardware differences (ie: SATA vs. IDE, whatever else).

Also, I wonder if the web interface improvements could be backported as well.

It must be processor speed and XFS file system, possibly some gain from Samba 3 vs 2.
I can't imagine that SATA vs PATA would be all of it.

certainly I was dissapointed to see how lackluster the performance of my HG was in comparision :down:

Samba slates the processor. Any processor speed improvements will be seen as write/read improvements too. XFS is a better system but I think ALL the gains shown here are with the better processor. NFS performance testing would have been a better test.

XFS is not as robust as desired when power outages and the like occur, from what I've heard. You might want to check if it's right for you before switching to it.

XFS also stems from SGI (chapter 11 reorganisation). JFS is also okay but is iffy. ReiserFS maybe the route to go for performance. ext3 is very slow compared to these others. What do you think andre? Off topic I know!

I don't know much about filesystems, but my kernel 2.6 comes with a number of alternatives to ext3 in module form for people willing to switch.

My personal opinion, for what it's worth, is, ext3 might be wasting space and not deliver peak performance when it comes to small files, but it's mature and robust in emergency situations. And it's faster than the ethernet connection in any case. The only drawback is, your chance to recover deleted files is small. I don't know if ReiserFS would be more forgiving in this respect?

ReiserFS is much faster when used with smaller files or web server systems. This is because most of the protection that ext3 offers is not their. It is still a journaled file system but provides much BETTER performance. The down side is that you may loose cached data in the event of a failure. The ext3 provided on the LS is much better on recovering following sudden power outages/system loss. I may move over to Reiser as I do not suffer any of these such problems. Maybe XFS is worth considering if Buffalo have decided to go in that direction: support may be poorer though.

speaking of which, what transfer rates have you seen with NFS?? Anyone with an HG(Gigabit ethernet) use NFS?

Fifilein had done a performance test with Bonnie+++ to test AES/DMcrypt against my EncFS numbers. But he also included numbers for XFS and ext3 as well, take a look:

i do not know if we will need JTAG at all for the LS Pro, but it would do not harm to have a safety net.

i searched a bit in the internet and found this commercial solution:

http://www.ronetix.at/flash-programmer.html

i sent them an email just out of interest about the price.

the telnet-binary is a already on the LS-Pro.

http://66.249.93.104/translate_c?hl=de&ie=UTF-8&oe=UTF-8&langpair=ja%7Cen&u=http://www.yamasita.jp/linkstation /0607/060727.html&prev=/language_tools

there is a line for telnet that is only commented out.

to get telnet access we will either have to

1) modify the image.dat (or how it is called for the LS Pro)...then it could be easily flashed. problems might occur with a changed password of image.dat

2) open the LS Pro and connect the SATA HDD to a Workstation. modify its the linux partition and then put it back inside.
there does not seem to be anything like the ext2/ext3-magic number-problem which was invented by melco/buffalo. at least it does not look like on the japanese pages.

3) attach a serial as i think the japanese guy did and uncomment the line that way.

2 & 3 open us the way for analysing the update process which will have changed a bit because of u-boot and we will be able to find out the password with this method http://www.sowbug.org/mt/archives/000179.html....with the password we can easily modify the image.dat again.
-------
i also found out that the watchdog for the AVR is now called daemonwatch and it is called this way:
/usr/local/sbin/daemonwatch - a /etc/daemonwatch.list

I would expect the new watchdog would monitor volts, temp and fan as does the tera's.

i just wanted to mention that we already know the password for the hddroot.img (=image.dat) + initrd.img(=ramdisk) here in the main thread.

http://buffalo.nas-central.org/forums/index.php?action=vthread&forum=16&topic=1364

the password is

some LS-GL news
1) the LS Pro can easily power 2 Sata-HDDs....he writes it that way that it did not work with all other boxes...

http://66.249.93.104/translate_c?hl=de&ie=UTF-8&oe=UTF-8&langpair=ja%7Cen&u=http://www.yamasita.jp/linkstation /0610/061013.html&prev=/language_tools

2) and here is it....a Benchmark.

http://66.249.93.104/translate_c?hl=de&ie=UTF-8&oe=UTF-8&langpair=ja%7Cen&u=http://www.yamasita.jp/linkstation /0610/061014.html&prev=/language_tools

Code:
Machine     CPU       Clock     Bogo MIPS 
HD-HLAN V1   PPC       200MHz    130.66
HD-HGLAN     PPC       266MHz    173.26
LS-GL        ARM       400MHz    266.24


so the LS Pro is much faster then the other boxes!

3) the most important thing comes at last:
he crosscompiled the kernel from the GPL Source + the supplied .config(buffalo/buffalo_lsgl_arm_100.config) and successfully booted it!
obviously he used the cross-toolchain from code sourcery.

translated:
http://66.249.93.104/translate_c?hl=de&ie=UTF-8&oe=UTF-8&langpair=ja%7Cen&u=http://www.yamasita.jp/linkstation /0610/061015.html&prev=/language_tools
original (better code readability):
http://www.yamasita.jp/linkstation/0610/061015.html

guys....that last thing is awesome....first thing to do will then be to compile a bunch of additional kernel modules.....
later the way should be to create a diff of the 2.6.12 kernel from kernel.org and the GPL-one....we have to look at the crucial stuff, create a patch again if needed....apply it to the 2.6.12 kernel from kernel.org and then apply an incremental patch to the latest kernel...

The same as what Buffalo used to create the thing in the first place. Hopefully, Javascout is having the same luck with his kernel build. Maybe this will be available for download soon?
