Document URL: ------------- https://access.redhat.com/documentation/en-us/red_hat_gluster_storage/3.2/html-single/administration_guide/#sect-NFS_Ganesha Describe the issue: ------------------- For better large file performance,it is recommended to set the following tunable on all workload generating RHEL 7 clients : sysctl -w sunrpc.tcp_slot_table_entries=128 echo 128 > /proc/sys/sunrpc/tcp_slot_table_entries echo 128 > /proc/sys/sunrpc/tcp_max_slot_table_entries The tunable is to configure the number of outstanding RPC requests to the NFS server. And do a remount post this. To make it persistent on reboots : echo "options sunrpc tcp_slot_table_entries=128" >> /etc/modprobe.d/sunrpc.conf echo "options sunrpc tcp_max_slot_table_entries=128" >> /etc/modprobe.d/sunrpc.conf
The steps are added under section 6.2.4.6. Accessing NFS-Ganesha Exports: http://ccs-jenkins.gsslab.brq.redhat.com:8080/job/doc-Red_Hat_Gluster_Storage-3.2-Administration_Guide-branch-3.2-Stage/lastSuccessfulBuild/artifact/tmp/en-US/html-single/index.html#sect-NFS_Ganesha
