May 02 11:22:09 <willem> It is abnormal to have a write speed of 950kb/sec (tested with hdparm) on an external usb disk, isn't it? 
May 02 11:22:35 <willem> it takes almost to minutes to write a 100mb file ...
May 02 11:22:51 <willem> the thing is that on a windows pc, the disk performs ok
May 02 11:23:17 <willem> I have installed the openwrt firmware (kamikaze) on my nslu2
May 02 13:55:23 <ShadowJK_> I hope you havent mounted the disk with -o sync
May 02 13:55:40 <ShadowJK_> ( check /proc/mounts )
May 02 14:31:28 <willem> nope, async
May 02 14:31:50 <willem> ShadowJK_: I use a 1TB disk, I assume that's to big for good performance?
May 02 14:34:04 <Reedy> whats size got to do with performance?
May 02 15:07:26 <willem> Reedy: do you have any other explanation for the slow behaviour?
May 02 15:09:07 <Reedy> From an NSLU2?
May 02 15:09:16 <Reedy> The Network, The Ram, The CPU, the USB...
May 02 15:13:19 <willem> oke, but why have several users such high performance and me such low performance
May 02 15:13:27 <willem> the only difference is the external hard disk
May 02 15:15:06 <Reedy> No one gets high preformance
May 02 15:15:10 <Reedy> What speeds are you getting?
May 02 15:15:52 <willem> Reedy: less then 1mb/sec for reading/writing
May 02 15:16:24 <willem> doing a dd bs=1MB count=100 if=/dev/zero of=test.img takes ages
May 02 15:20:33 <Reedy> where are you when your running that command
May 02 15:22:01 <willem> I simply mount the external usb disk and put that test.img on the usb disk
May 02 15:23:22 <Reedy> so your in some folder on that disk?
May 02 15:24:19 <willem> uhu, but i get the same bad performance when running hdparm or using smb to transfer some files
May 02 15:28:02 <Reedy> what drive/caddy is it?
May 02 15:33:05 <willem> western digital elements 1TB
May 02 15:59:13 <Reedy> Got the external power plugged in?
May 02 15:59:56 <ShadowJK_> heh
May 02 16:00:27 <ShadowJK_> I think that disk doesnt even try without external power
May 02 16:01:06 <willem> ShadowJK_: uhu thats correct
May 02 16:01:23 <willem> and that would still be weird since the same disk setup works fine with linux/windows
May 02 16:01:46 <Reedy> I was just making sure :P
May 02 16:01:51 <willem> hehe
May 02 16:01:59 <Reedy> What OS have you got on it?
May 02 16:02:03 <willem> tomorrow I will have different hardware to test
May 02 16:02:12 <willem> i had openwrt on it
May 02 16:03:14 <ShadowJK_> with hdparm -tT I get 5.32 from a usb flash drive, 5.87 from a seagatte freeagent usb harddrive
May 02 16:03:37 <willem> i get 922kb/sec
May 02 16:03:43 <willem> thats almast 6 times slower
May 02 16:03:51 <willem> s/almast/almost
May 02 16:10:05 <CIA-14> 03bzhou * r10036 10optware/trunk/make/mod-wsgi.mk: mod-wsgi: 2.3 -> 2.4
May 02 16:15:54 <willem> ShadowJK_: do you have a 1TB disk?
May 02 16:18:47 <ShadowJK_> no
May 02 16:18:54 <ShadowJK_> not connected to nslu2 anyway
May 02 16:20:18 <mwester> There's nothing magic about the size of the disk.
May 02 16:20:41 <willem> mwester: but why that bad performance?
May 02 16:21:12 <mwester> I don't know -- but it's certainly not the size.
May 02 16:21:39 <mwester> What does hdparm tell you?
May 02 16:22:49 <willem> read and write speeds < 1mb/sec
May 02 16:22:59 <mwester> Do the command ShadowJK_ suggested with hdparm; that will tell you the speed to the disk itself.  The dd command has to write to the filesystem.
May 02 16:23:16 <mwester> Show me the command and the output (pastebin)
May 02 16:24:11 <willem> i am installing debian on it right now, but i did hdparm -Tt /dev/sda and I got two results, each around 922kb/sec
May 02 16:24:31 <ShadowJK_> The first result from hdparm -tT shouldn't be 900-ish..
May 02 16:25:04 <willem> i did -Tt but still, both where around 9xx
May 02 16:25:10 <mwester> What were you running on it before you started installing debian?
May 02 16:25:24 <willem> openwrt
May 02 16:26:06 <mwester> Wow.  :-o So you are going from one extreme to the other!
May 02 16:26:19 <mwester> Ok, well, I can help you with neither, really.  
May 02 16:26:30 <willem> what do you suggest to install?
May 02 16:27:04 <mwester> You don't state your needs; I presume you have studied the firmware page on the wiki and selected your choices carefully.
May 02 16:27:33 <willem> uhu but why do you see debian as an extreme choice?
May 02 16:28:10 <ShadowJK_> in the tiny - huge scale you went from one extreme to the other
May 02 16:28:49 <mwester> OpenWRT is the smallest firmware, Debian is the biggest firmware, what is interesting is the neither of those two actually has any of the developers for them on the nslu2-linux project.
May 02 16:29:40 <mwester> So your disk issues would need to be discussed on the openwrt channel for the one, and on the debian-arm channel for the other!
May 02 17:46:06 <willem> what other root passwords can be used after installation rather than opeNSLUg, root, and all of my other previous root passwords?
May 02 17:46:10 <willem> none of them work
May 02 18:15:19 <mwester> Depends on the firmware you installed.  I have no idea what it would be on Debian.
May 02 18:33:39 <CIA-14> 03msergeyy * r10037 10optware/trunk/make/lftp.mk: lftp: 3.7.11 -> 3.7.13
May 02 18:35:43 <willem> mwester: nevermind, I was using the wrong IP address =)
May 02 19:35:29 <ShadowJK_> heh
May 02 19:35:43 <ShadowJK_> any hdparm results on debian yet?
