How slow is it? May the code that reads is relevant too.

Hi,
I am new to hadoop. We are evaluating HDFS for a reliable, disitrbuted file
system use.
From the tests (1 name + 1 data, both on different RHEL 4 m/cs, client
running on the name node m/c) I have run so far:
1.The writes are very fast.
2.The read is very slow (reading a 68 megs file). Here is the sample code.
Any ideas what could be going wrong:
public InputStream select(String sKey) throws RecordNotFoundException,
IOException {
DistributedFileSystem fileSystem = new DistributedFileSystem();
fileSystem.initialize(uri, conf);
Path path = new Path(sKey);
FSDataInputStream dataInputStream = fileSystem.open(path);
return dataInputStream;
}
Thanx,
Taj
