Dose extracting 6 GB RAR file take 40 minutes !? or something wrong !

kimoo

i downloaded a 2 pieces RAR file that both about 6 GB , it's in C: , i tries to extracting it to drive E: but it seems that toke about 40 minutes , is it normal or something wrong ? i feel it's so long time cause i'm in AMD A10 4 Core processor now ,
i use win7 32bit ,

How much space is available on drive C? I'm presuming the program is going to assemble the file, verify it against some checksum, then copy the result to your destination, so drive C would need enough space for the extracted file.

and here i move a file from C: to E:

i think there was only 4 GB free in C: , is it the reason ?

@kimoo That could be part of the issue.

If C: is a hard drive (HDD), you could try defragmenting it with the Windows Utility "Defragment and Optimize Drives".

If there is free space scattered throughout the drive in small chunks since it is almost full, then the write head of the HDD will need to jump around the hard drive platter to fill in the spaces. Defragmenting will allow the write head to stay in one spot while writing data, so it should be a bit faster.

If C: is a solid state drive (SSD), then it will slow down as it is filled to its capacity. Defragmenting will not help with an SSD. The best you can do with an SSD is try to not let it get too full.

I think it has something to do with the size of chunks of data it can write at a time. Something like the controller needing to copy data from a chunk and move it to a cache/RAM before writing it back with the new data. A less filled SSD wont have this problem because there is enough free chunks to not need to squeeze more data into a partially filled chunk.

There also might be something to do with a section of single level cells (SLC) that are used as a sort of cache being filled up with actual data, but not every drive has this, so I won't go into any more detail.

Is C the OS partition?
What size does it has?

4Gb free before or during the extract?

That would be a reason for a slow function.

it's HDD one , a Seagate 500G

yes C: is the OS drive
4 free during the extract , now after deleting the file free space is 10 G , the whole C: is only 20G as i only use WIn7 32 now , will move so soon to 64bits one and may resize the drive to move space

@nomadic @sgunhouse @Zalex108

there is strange thing with me also
When my HDD busy in something , the whole computer be so slow .
for example after IDM finish downloading it rebuilt the file , in that time during rebuilding the computer be so slow , if i opened the task manager during it i will find that the CPU is only busy between 6-16 only !! it's not 100% busy to make the computer slow , so why this happened ?? i don't remember that was happened in my old P4 computer witch had a 80G WD HDD

my current HDD is Seagate 500G in AMD A10 PC

so what the reason exactly ? why the whole computer be so slow if the HDD were busy in something ?

@kimoo

Already explained.
System needs it's free space to work: Swap, Cache...

Go for the mentioned steps in other posts.
Look for an optimize Windows 7 guide too.

As commented,

If you move your Docs, pics, vids... folders from C, will free some valuable space, maybe enough to make system work fine or better.

Look for Tree Size File to check what is ocuping the space.
