As I said, transfer speed for medium/big files is fine enough, the problem is for small files.
I just asked if some of you experienced the same issue with the same configuration (hetzner VM + storagebox) and if there is a way to improve performances or if I need to find something else that would match my needs

Hi

I got a similar configuration with a CPX21 instance connected to a BX21 Storagebox.
While transfer speed for large files is fine, transfer speed for large amount of small files is horrible:

root@nextcloud:~# for f in {1..2000}; do mktemp ; done 
/tmp/tmp.qabMyUDO5N
/tmp/tmp.QPuk8CcXSB
/tmp/tmp.NhErmerWFl
/tmp/tmp.CtkY3jvTbL
[...]

root@nextcloud:~# time cp /tmp/tmp.* /backups/test/
real	4m20.998s
user	0m0.061s
sys	0m0.565s

root@nextcloud:~# time rm -fr /backups/test/*
real	1m36.682s
user	0m0.050s
sys	0m0.196s

Are you experiencing the same behaviour ?
