SOLVED Slow Write Speed to NAS

[corin.corvus]

Hi,

i build a testnas with my old 4 Core Intel 4460, 16 gb DDR3 Ram and the Mainboard MSI H81I.
The Truenas OS is on a USB SSD Drive and the Pool Drives are over SATA.

Now i add a pool on a single WD Red 4 TB with 5400rpm and add a Dataset SMB with a smb share and copy some data on the Storage. I enables Compression LZ4, but not enabled ZFS Deduplication. My Write Speed is under 10 mb/s all over the Time with small and big Files.

Source: Linux server
Destination: Truenas Pool
Connection: 1gbit LAN with 1 Switch
No other Traffic at this Moment.

Show : Dataset

I know the HDD can more. In my old NAS the same copytask was over 80mb/s.
how i can improve the performance? May the System Drive on USB SSD is the problem (cache)?

Thanks

dont test with 'copy" - use a write or read test first.

see if its a nas isssue or a copy issue

I think you mean similar like iperf?

Mainboard MSI H81I.

Yeah, this is a crappy Realtek based ethernet mainboard and is not expected to perform well. The network test you're showing would be typical of Realtek.

May the System Drive on USB SSD is the problem (cache)?

No.

10 mb/s

80mb/s

This is ambiguous. These are technical forums, please do not make up your own abbreviations for units. These both could be read as either megabits per second or megabytes per second. That's an order of magnitude variation.

Terminology and Abbreviations Primer

We realize that new users have a lot to learn when they come to FreeNAS. There's a certain amount of confusion added to discussions when users pick random/approximate terms to describe things. I've spent a lot of time quietly trying to translate terms on the reader's side when reading posts...

The Networkdevice work well normally. Before i installed truenas, i used this board with Proxmox. The Performance was better than this. I removed proxmox, cause the cpu performance was not so good for a hypervisor.

I learned:
mb/s every time is megabyte
mbit/s is every time megabit

Its not ambigous. Look in the Wiki and much other Definitionswebsites:

Megabyte - Wikipedia

It *is* ambiguous; nowhere in your listed charts is "mb/s". Capitalization is significant. These are SI metric prefix units. A small "m" is milli, as in 1/1000th, while a capital "M" is Mega, as in one thousand. I also specifically pointed you at the Terminology and Abbreviations Primer on these forums, so I don't really care about your "Wiki and much other Definitionwebsites".

i dont care "case sensitive". if i mean mbit, i write mbit. my mega is a small mega.

Please lets get back to topic.

Forcing other people to translate what you mean, refusing to follow the norms of an international standard, is not particularly conducive to getting assistance from people who are here discussing these topics for free. Personally I feel it's rude to refuse to follow community norms in such a fashion. We all know that there's a lot of misusage out there, which is why we generally try to educate users on this.

Please lets get back to topic.

Clarifying what you mean is very much on topic. There's a huge difference between 10MBytes/sec and 10Mbit/s. Order of magnitude. I have a decade's worth of observation that says a clearly, well communicated problem is much more likely to result in engagement by the community. Part of my role as a moderator is to help you get that help.

I solved my problem now. It was the Gateway that make trouble sometimes.

Thanks

What do you mean by it was the Gateway, can you please tell how you fixed it im stuck on 6hours transfer time for 30gb

Welcome to the forums.

Sorry to hear you're having trouble. Please take a few moments to review the Forum Rules, conveniently linked at the top of every page in red, and pay particular attention to the section on how to formulate a useful problem report, especially including a detailed description of your hardware.

You've basically given no one anything to work with, so the responses will tend to be random guesses rather than anything useful.

Not the way to be, nor act, you can not change industry standards as noted because you are too lazy to properly type something out which can confuse the meaning for others.

Why not try to just take the advice of experts in the area and type something out as it should be vs just making your own version?
