Hi guys,
Our TSM 7.1 servers (with directory containers) were suffering from a very slow response for a long time. We already applied the kernel parameters specified in the installation guide and the SP Blueprints, but since we recently changed several other kernel parameters in one go, thing improved a lot. It’s still not great, but at least it’s not taking ages anymore to set up a new client session.
I’m interested in the value you are using on your Linux servers, especially for servers with a large workload on directory containers. If this is the case, can you please send me the output of the following commands:
sysctl vm.dirty_background_ratio
sysctl vm.dirty_ratio
sysctl vm.dirty_expire_centisecs
sysctl vm.dirty_writeback_centisecs
sysctl net.core.rmem_max
sysctl net.core.wmem_max
sysctl net.ipv4.tcp_rmem
sysctl net.ipv4.tcp_wmem
sysctl net.core.netdev_max_backlog
sysctl net.ipv4.tcp_moderate_rcvbuf
sysctl net.ipv4.tcp_no_metrics_save
Thank you VERY much for your help in advance!
Kind regards,
