Tiny Core runs off RAM?

[flawd]

So from what I understand, and correct me if I am wrong here, each time the PC boots up... the Linux Kernal and Core.gz  file are copied from the boot partition and run on your Memory?

How do I check if I am running off Memory/RAM? How do I test the read/write speeds if it is running, wil hdparm work?


Sorry if some of the questions may seem silly, just starting to learn more about linux.

You are correct, in tinycore vmlinuz and core.gz are loaded in ram and run from there.

By default extensions are loop mounted, but you can set the copy2fs flag using the apps gui and load all extensions to ram.

There is an hdparm extension - I'm not sure if it tests read/write speeds with a dummy file(s) or not.

You can check R/W speed using dd command

Thanks for tips guys.

I looked up the dd  command,

Code: [Select]

dd if=path/to/input_file of=/path/to/output_file bs=block_size count=number_of_blocksIt also said I had to mount the drive then navigate into it via terminal and run the command.

Code: [Select]

$ dd if=/dev/zero of=./largefile bs=1M count=1024But where am I navigating to in this case? It wouldn't be /dev/sda?

Are these the loops I have been seeing when I run ps? There are 34 processes start with loop0-loop33, I was wondering what those were.

You should use "time" command combined with "dd" command to measure.

Hi flawd

Yes, those are extensions.
If you use the  dd  command from  coreutils.tcz  it gives transfer rate:

Code: [Select]

tc@box:~/findpcs/src/rollcall$ dd if=/dev/zero of=./largefile bs=1K count=10
10+0 records in
10+0 records out
10240 bytes (10 kB) copied, 0.000346467 s, 29.6 MB/s
tc@box:~/findpcs/src/rollcall$Be very careful using the  dd  command. If you get the  of=  parameter wrong you can easily wipe out a hard drive.
