[ovirt-users] Re: ovirt-imagio-proxy upload speed slow

Hello, We have the same problem. It's seems that the ovirt-imageio-proxy is the bottleneck for our setup. We use vprotect to backup a VM via api We ask for support with vprotect team and we are currently tunning some parameters on the kernel. We have full 10G network in ou setup. Here is the kernel parameter that we set. Did you manage to progress on the speed process ? # Maximum receive socket buffer size net.core.rmem_max = 134217728 # Maximum send socket buffer size net.core.wmem_max = 134217728 # Minimum, initial and max TCP Receive buffer size in Bytes net.ipv4.tcp_rmem = 4096 87380 134217728 # Minimum, initial and max buffer space allocated net.ipv4.tcp_wmem = 4096 65536 134217728 # Maximum number of packets queued on the input side net.core.netdev_max_backlog = 300000 # Auto tuning net.ipv4.tcp_moderate_rcvbuf =1 # Don't cache ssthresh from previous connection net.ipv4.tcp_no_metrics_save = 1 # The Hamilton TCP (HighSpeed-TCP) algorithm is a packet loss based congestion control and is more aggressive pushing up to max bandwidth (total BDP) and favors hosts with lower TTL / VARTTL. net.ipv4.tcp_congestion_control=htcp # If you are using jumbo frames set this to avoid MTU black holes. net.ipv4.tcp_mtu_probing = 1
