NASLite Network Attached Storage

hey guys,

even system is @ idel no one is logged in its still say's mem usage 98%? why is that?

system spec:-
p3 800mhz
340mb ram
1x250gb
2x4gb

Thanks

The usage at 98% is valid since the kernel will not offload mem pages
unless the space is needed by another process. The idea is that if a
page is in RAM, then it's likely that the associated process will be
called again. Keeping the page loaded keeps response time down. In
addition, a lot of the RAM is used by networking/disk-access buffers in
order to keep disk writes to a minimum. Those are not the same as
buffers you see when you issue a "free" command.

Point is that if the RAM is available, there is no use freeing it since
NASLite owns the hardware and does not have to yield to other processes.

I have the same problem with naslite 2 usb.
This is my hardware:

n° 1 Cpu AMD Athlon 1000 Mhz on MB ASRock k7.
N° 1 256 MB DDR 400
N° 1 HDD Maxtor 300 Gb SATA
n° 1 Pen Drive 128 Mb USB 2.0

Boot on Pen Drive with partition mode, 'couse I' dont know the difference between Partition and SuperFloppy.
I think that partition mode is more faster but not shure.

My client are 3 PC with Windows XP Home and when transfer large files between client with windows and NAS the memory of nas is 98% and the trasfer is no faster.

For faster transfer e more ram free I must install more ram?
For example 512 mb

I have also a cpu AMD XP 2000 Mhz is better to install it?

Thanks a lot in advance and sorry for my bad English.

Adding more memory should help but the faster CPU will likely yield no improvment in transfer rates. Also there is a limit to how fast the data will transfer over the network. If you are running a 100Mb network it is around 10MB/sec give or take a little.

Thanks mike for reply.
So I add 256 mb more total 512 mb and sobstitute the amd 1000 mhz with amd 2000 mhz.
What is the difference between 1000 and 2000 on NAS lite box?

Thanks again.

I said add the memory but don't waste the time on adding the higher speed processor. You will very likely see no preformance increase at all.

Best,

Mike

Hi Mike,

I'm trying to understand just where the "envelope" might be with memory additions. Just where does one typically hit the point of diminishing returns for memory investment?

Have a lotta boxes to configure, and your insight has real economic consequences.


Thanks,

BTW, I'll confirm your claim as to modest processor performance. According to the net gear utility...I'm seeing 70-86MB/sec transfers into an NAS lite with a 600mhz Via Samuel CPU. Very pleasing results for such a low powered box.

I think tony and Ralph said that 512MB is a really good number, also easy to achieve with just a pair of cheap DIMMs. I dont think that the OS supports greater then 1024MB anyway.

I think Mike has stated that a max of around 768 meg RAM is as much as NASLite can use...
