[PVE-User] Linux improvements for ceph and general running vm's

[Gilberto Nunes]

Hi there

Can any one tell me if this options bellow can improve somethings related
network:

net.ipv4.tcp_low_latency = 1
net.core.rmem_default = 10000000
net.core.wmem_default = 10000000
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216

net.ipv4.tcp_rfc1337=1

net.ipv4.tcp_window_scaling=1

net.ipv4.tcp_workaround_signed_windows=1

net.ipv4.tcp_sack=1

net.ipv4.tcp_fack=1

net.ipv4.tcp_low_latency=1

net.ipv4.ip_no_pmtu_disc=0

net.ipv4.tcp_mtu_probing=1

net.ipv4.tcp_frto=2

net.ipv4.tcp_frto_response=2

net.ipv4.tcp_congestion_control=illinois

Thanks a lot

Hi,

do you want to improve latency or throughput ?


They are lot of thing to tune in ceph.conf before tuning network.
can you send your ceph.conf too ? (ceph cluster && proxmox nodes if ceph is outside proxmox)

ssd ? hdd ?
