CPU to slow for SCP transfer?
i have a vps (openvz) at hostsailor, which is solid so far, but i habe problems with scp transfer to my local machine with winscp, the transferspeed is slow (about 1MB/s) and CPU is at 100% load. Hostsailor already suspended my vps once, because of high cpu load for a few hours. Trough http i get fullspeed and cpu-usage is very low.
I did some research and changed the encryption algorithm from aes to blowfish, but that doesn´t help. Compression is turned off. Any ideas? OS is a standatd Debian 8 64bit image.
Even on my rpi2 at home i get about 5MB/s when downloading a file with scp.
thanks in advance
