s3 write speed is too slow - is there a way to speed it up ?? 20 times slower than NFS file system transfer !! ugh !!

[FFNye]

Hi I am new to s3 - moving from NFS to s3 but I am not happy with the write performance!!

HOW can I speed it up ? some config parameter that move larger packages ?
or is it your setup the hardware - ie hardware parameters ?

Now s3: around 10MB/s vs our regular NFS filesystem 200MB/s ie 20 times slower !!!! ugh
s3cmd version 2.1.0
