<br>
wow, good hint! We switched from old servers with version 4.1.6 to new<br>
servers (fresh install) with version 5.3 on february 5th. I saw that<br>
there was more network traffic on server side, but didn't watch it on<br>
client side - the traffic went up significantly on both sides, from<br>
about 20-40 MBit/s up to 200 MBit/s, on server side from about 20-40<br>
MBit/s up to 500 MBit/s. Here's a screenshot of the munin graphs:<br>

network traffic on high iowait client:<br>

<br>
Don't know if that's related to our iowait problem, maybe only a<br>
correlation. But we see the same high network traffic with v5.3.<br>
<br>
<br>
Thx,<br>
