Hallo,

top zeigt mir folgendes an
Cpu(s): 0.0% us, 11.1% sy, 2.8% ni, 0.0% id, 80.6% wa, 2.8% hi, 2.8% si

| Quote: | wa
The wa column details the percentage of time the CPU was idle with pending local disk I/O and NFS-mounted disks. If there is at least one outstanding I/O to a disk when wait is running, the time is classified as waiting for I/O. Unless asynchronous I/O is being used by the process, an I/O request to disk causes the calling process to block (or sleep) until the request has been completed. Once an I/O request for a process completes, it is placed on the run queue. If the I/Os were completing faster, more CPU time could be used.
A wa value over 25 percent could indicate that the disk subsystem might not be balanced properly, or it might be the result of a disk-intensive workload. |

Meinst Du wirklich 4 mb (MilliBit)  oder doch eher 4MB (MegaByte)?
