Topic: My SME is soooOOOO slow.

[siXXXeight]

My SME is soooooo slow.
I want to use the SME only as Fileserver
The Web-Manager needs 20-30 sec to create a page.
The Filetransfer is superslow. Only 5-10% of maximum Wirespeed (100Mbit-LAN - checked with a Monitor-Tool on my Switch), sometimes with interrupts for 1 or 2 sec. If i made a Filetransfer with 2 other PC's I reach 50-60% Wirespeed (that's normal). I use in nearly all PC's the same LAN-Cards - also in my SME.

My System:
SME-Server:
PII-233, 100Mbit switched LAN, 2 (SW-Raid) HD 40 GB (jupered on 32GB), 256 MB SD-RAM,
Clients:
diff. PC with w2000, ME, 98, XP

I've checked the filetransfer with a sniffer.
So i could see than theere is a transmission for 3 seconds and a "freeze for 5 sec.

Was it an upgrade, or a fresh installation ?
I upgraded from 5.1.2 and have the same problem in manager really slow.

[Jeremy England]

I also have the same problem, however mine was fresh installation, sorry cant help you out

[siXXXeight]

to guillermo:
its an fresh installation !!!
i've made a SME-installatin on an AMD-Duron 700-System and it works well, but this is a realy fast Hardware.
I'll try an new installatin on a new hardware and give a feedback.

[Matt Thompson]

I have a similar problem - accessing the web interface can sometimes be VERY slow! (slower than a 56k connection), then at other times it is as quick as you'd expect on a 10Mbit network.
Mine is a fresh installation on a PII-300.
Cheers,
Matt

Just a thought -

If at all possible use DHCP service from the SME box.

Rob,
How would that help? I ask as its not possible and wonder if there is another way to help speed it up.
Cheers,
Matt

Listening to get knowledge ! Hope it's OK !

Dhcp will supply all the correct DNS and gateway info to your client PC. My comment is based on the possibilty that the time delays are related to name resolution.

Try http://:980 and see if that is any quicker re: opening server-manager

[Mike]

I'm using a fresh install of 5.5 on a cheensy machine. However, there appears to be a problem with the server manager. It's timing out on me. More, specifically, the left pane never displays. It's not a problem with name resolution as I'm using the IP address instead of its domain name.

[Matt Thompson]

Sorry Mike but this isn't going to help you, but using the IP address shorted out my problem. thanks Rob.

[sixxeight]

the Problem is still the same!!!
I've smashed my PC and installed the SME on an new AMD-Duron 800 System with 256 MB SD-RAM (I think a Powerfull System). Now I have no problems with the Server-Manager but the Fileupload is very slow (max 20% of Wirespeed - 100Mb-LAN) an every 10 sec with interrupts for 2 sec. On download I have no interrupts but the same slow transferrate.

I can't help you, but I can commiserate.  I've noted the same crappy throughput on every e-smith box I own -- I have 4 of them, and I can't get anywhere near 100Mbit between any of them.  It doesn't matter what switch I use, or even with a straight crossover cable NIC-to-NIC.

First read this -

http://linux.oreillynet.com/pub/a/linux/2000/06/29/hdparm.html

then read this-

http://myezserver.com/downloads/mitel/howto/hdparm-howto.html

then search hdparm on the boards. While we enable hdparm on all our Servers (celeron 900+ and pIV 1.2+  -  we find that AMD's run too hot for servers) and have had no problems (yet) many have reported serious file system corruption.

We get disk reads of 20mbps with hdparm enabled and 2.5mbps with it disabled.

We found that the /sbin/e-smith/signal-event post-upgrade command will disable hdparm. This is run after the most recent updates are applied and is also run as part of the desktop restore.

FYI the hdparm "feature" outline in Darrells howto will be dropped from 5.6

WOW - thanks....

To be replaced with something considerably better.

Copy /etc/sysconfig/harddisks to /etc/sysconfig/harddiskhda and then edit that file to choose exactly the IDE interface settings you want for your first hard disk. Repeat for hdc, and.or for any other IDE hard drive you have. Then reboot.

Does anyone know of any "with it" HD manufacturers that provide recommendations for HDPARM use??

[Lightman]

Hi!
Just to check, what kind of network card did u use?.

It's weird, I have SME 5.0 running on a P166 , 64Mb ram 10gig hd
and 2, 3Com (905C and 905B) and always get about 90% net capacity
in readings and about 60% in writings (due to the small intervals when
the HD writes data and no lan traffic, I think it's because of the low ram).

tryed in a friend's server with Pentium II 300 slot 1, 128mb ram soyo
intel mobo and 20 gig hd, and get about 70-80% in writing a 500 mb file.
and a sustained 90% reading all the time.

all of this is with 3com network cards and 3 com hubs, all 100mbit network.

I think that AMD is not very good for servers, anyway, and the these
3com boards helps a lot when speed matters.

see you

i've installed my SME on a 2.5" IBM-HD UDMA 66 and add 2 40GB HD's for software-raid. In this configuration hdparm works well. If i try to install the SME to an 10 GB 3.5" HD (I've tried different models , all UDMA 66 or 100) hdparm didn't work. All installation are on the same computer und with the same BIOS-settings.
I type in console "hdparm -X69 -d1 -u1 -m16 -c3 /dev/hda". All settings are accepted and work well but after reboot they're gone.
WHAT CAN I DO ????

...or what's my misstake

Hi

Did you put the command in the rc.d ?, so it will be loaded every
time you start the system?.

I have added the following line to /etc/rc.d/rc.local file:

hdparm -X66 -d1 -u1 -m16 -c3 /dev/hda

don't know if this is the best place to put this command, but
works fine for me .

could done it better but it work so fast with this parameters
that i didn't wanted to expermient beyond that

My HWD is: PII-350 100mhz fsb, 128 Mb ram, 8gig seagate ata66
drive, and 2 3com nic.
