Performance problem using clustered samba via ctdb
....dat 5)
on the shared filesystem. On one node I get a value of about 36000. If I
run the very same ping_pong-command on all four nodes I get a value of
1000 on each node.
On our old samba servers we have a total of about 400 connects
distributed on two servers. However if I try to put such a load (4x100)
on the four new samba cluster nodes via smbtorture the test won't even
start. If i put 400 clients on one of the servers it works just fine.
Now I ask myself two questions:
1. Is the nbenchmark kind of realistic test?
2. Why do throughput rates drop as much as I found out and is this a
known...

Column Extraction from matrix
Hi all,
I have a 4 by 100 matrix. I wish to extract each column and make it into a 2
by 2 matrix.
I also want to assign names for each 2X2 matrix.
For example
set.seed(2)
a=matrix(rnorm(400),ncol=100)
a1=matrix(a[,1],ncol=2)
a2=matrix(a[,2],ncol=2)
.
.
.
a100=matrix(a[,100],ncol=2)
Any simple ideas. Thanks.
B
