Hi Vikas,
I have already loaded performance translators, if I want to increase nodes
to improve the performance, client or server nodes you suggest to increase?
Thx !
Ben
For Client side:
volume iothreads
type performance/io-threads
option thread-count 8
option cache-size 128MB
subvolumes storage-unify
end-volume
volume readahead
type performance/read-ahead
option page-size 128kb ### in bytes
option page-count 64 ### memory cache size is page-count x page-size
per file
subvolumes iothreads
end-volume
volume writebehind
type performance/write-behind
option aggregate-size 131072 # in bytes
option flush-behind on
subvolumes readahead
end-volume
volume io-cache
type performance/io-cache
option cache-size 512MB # default is 32MB
option page-size 256KB #128KB is default option
option force-revalidate-timeout 7200 # default is 1
subvolumes writebehind
end-volume

You can try loading the following performance translators and see if it
helps:
* io-threads: load this just above your storage/posix translators on
the servers
* read-ahead: if your applications mainly make sequential reads, loading
this translator on the clients will increase throughput.
* write-behind: if your applications are write-intensive, loading this
translator on the client side may help performance.
