The following best practices apply when you mount ECS NFS exports.
Use async
Whenever possible, use the
async mount option. This option dramatically reduces latency, improves throughput, and reduces the number of connections from the client.
Set wsize and rsize to reduce round trips from the client
Where you expect to read and/or write large files, ensure that the read or write size of files is set appropriately using the
rsize and
wsize mount options. Usually, you set the
wsize and
rsize options to the highest possible value to reduce the number of round trips from the client. This is typically 512 KB (524288 B).
For example, to write a 10 MB file, if the
wsize option is set to 524288 (512 KB), the client makes 20 separate calls. If the write size is set as 32 KB this results in 16 times as many calls.
When using the mount command, you can supply the read and write size using the options (-o) switch. For example:
# mount 10.247.97.129:/home /home -o "vers=3,nolock,rsize=524288,wsize=524288"
