svnserve poor commit performance

Hi,

I am suprised by poor performance of svnserve and not sure how can I improve
it.

Test case

I am on a Windows 10 laptop with i7 and SSD. (tested on Windows server too
with similar performance)

I am running both server and client on the laptop - so it doesn't go through
the network.

* 6000 binary files in one directory
* 2,5 GB

* Smallest file: 16 kB
* Median file: 256 kB
* Largest file: 16 MB

* svn 1.9 with default fsfs.conf (I tried tweaking compression level
and block size but it just got worse)
* I tried both CollabNet and TortoiseSVN distributions.

Then I execute from command line:

svn add *

svn commit -m "test"

Results

Commit takes ca 10 minutes and most of the time I see Transmitting file data
...

I can see in Resource Monitor that disk is doing something but it's not
fully utilized. I don't see any peaks on CPU/memory.

Why the "transmitting phase" should take so long?

Thanks

Jakub
