High I/O Wait times and TCP buffers?
Just wondering what correlation is there between a large send/receive buffer queue (TCP) and high I/O wait times as reported by iostat and other utilities? is there any relationship?
We have been seeing problems at our firm with high I/O waits and I cannot pinpoint a process that is causing this, but the netstat -n reports show that the buffers do get filled up.
Any thoughts would be helpful. Thanks.
