Hi all,
I'm doing some testing on a very simple test environment with 2
netbooks, yeah netbooks, each with an 100Mb/s network interface.
Downloaded and installed 2.8.4-orangefs (mode: aio-threaded)
my pvfs2-fs.conf is:
<Defaults>
UnexpectedRequests 50
EventLogging none
EnableTracing no

BMIModules bmi_tcp
FlowModules flowproto_multiqueue
PerfUpdateInterval 1000

ClientJobBMITimeoutSecs 300
ClientJobFlowTimeoutSecs 300
ClientRetryLimit 5
ClientRetryDelayMilliSecs 2000
PrecreateBatchSize 0,32,512,32,32,32,0
PrecreateLowThreshold 0,16,256,16,16,16,0

I mount tcp://netbook000000:3334 on /netb2 on each client
and
export, on each server, /netb2 with nfs.
On 2 other clients I mount the nfs-shares, each from a different server,
and test copy performance from the netbooks, with 2 different 1GB-files,
to local storage. But I'm not able to get more then 100 - 110Mb/s total.
I expected to get something in the region of 160-200Mb/s.
1 copy proces from server to client gives 80Mb/s
Do I expect too much ? I thought it should scale more or less lineair.
