Troubleshooting / Re: udp packet loss stats
« on: May 28, 2015, 02:55:52 PM »
Yes, I just found out my network is 100Mbps.  I need to figure out why two 1G ni
c connection only gives 100M under auto mode.

It is running in vmware esx

One other thing is my disk IO from graph reached between 700 and 800.  What does
it actually mean ?

i3-3240 2core 3.4G
HDD SATA 7200rpm 6Gb/s
Both sides got the same hardware

I only saw CPU from dashboard
CPU graphs did not show anything

3. No, "Low puts the datastore in receive mode. So its compatible with a peer in high".

Do not understand.  Both datastores are 0% (sending and receiving sides)

Test is with applied keys on I3 by using above mentioned setting.
On high mode
Feeding zipped(tared) data
Once network was over 8Mbit/s, udp started lossing packets.  Loss was  getting much more
obvious when bandwidth was over 10Mbit/s. Initially, I thought that bottle
neck was CPU but it was never over 25% from dashboard when under 20Mbit/s.
Then I guess CPU is not the reason.

Feeding txt data
Milege could go up to 50Mbits, then I guess CPU is issue again.

On low mode
Feeding zipped(tared) data
Bandwidth could reach 90Mbit/s without lossing packets and CPU never went over 10%.
But datastore seemed not working on low mode because it is always 0%.

On both cases, memory were never over 10%, then memory issue can be ruled out.

By using wireshark, I can see both high and low mode compress data.  As
datastore is gone on low mode, I guess datastore io could be the issue
and  searching dedup from datastore also could be the issue because without
datastore bandwidth went up very much.


1 Is CPU the issue or not (major or minor)?
2 Is Disk io the issue or not (major or minor)?
3 Is datastore gone on low mode ?

I guess edge mode is "low" mode now. 
Under low mode, it seems to me datastore never be used. 

1 clean up datastore
2 put wanos on low mode
3 iperf UDP test
4 datastore always 0 %

Please confirm and thanks

Sorry to keep you guys waiting.  I have been committing to something else lately.  This week should have chance move back to it.

General Discussion / Re: Wanos plus speed up and down
« on: May 11, 2015, 03:21:12 PM »
I am really confused here speed up and down.  Since wanos needs to be paired, if one end is "up",  the other end must be "down".  For example, if  speed up and down is 6/60 and "up" side is only 6, how could "down" side reach 60 ?

Testing hardware:
vsphere 5.5
4G memory (assigned to wanos virtual machine)
regular SATA disk

I will do it again with better hardwares and keys because i think bottleneck is express limits.  Key requesting emai
l has been sent.

just information to share
It is only my test
udp start dropping packets(with following iperf cmd):
iperf -c -b 7m  -l 50k -F file ( consisting of random numbers)

I have come across a situation that reset datastore box can not be checked after running iperf udp for a while

For udp peer up, would be possible to do followings:

1) entering two wanos ips in console (command mode)
2) after every reboot, two appliance would auto find each other and peer up with
out sending tcp traffic.


General Discussion / time delay on wanos appliance
« on: May 04, 2015, 11:24:02 PM »

Since optimization itself takes time,
I am just wondering  how much time wanos will spend on processing a packet for optimization in general ( compared to a wire without optimization )

Or how can i give a test to see it ?

udp port option does not seem working.
Please see the attached and client wanos is on
Rule 6 does not work (no bypass happens, no bypass for app with port 10030)
Rule 6 without port will work (bypass happens)
Rules entered only on the server side

 Optionally increase UDPPEERRATE=0.05 to UDPPEERRATE=0.1

Where can i do this ?


Features / Re: traffic policy missing ip and port pair
« on: April 20, 2015, 09:25:48 AM »
Sorry i did not make it clear.

For example:

App1 with port11 running on ip1  goes to ip2 with port12
App2 with port21 running on ip1  goes to ip2 with port22

Traffic App1 needs to be optimized
Traffic App2 needs not to be optimized

current traffic policy fields only allows to enter ip only


Features / traffic policy missing ip and port pair
« on: April 17, 2015, 07:53:29 AM »

We have situation that certain traffic between two IPs need to be bypassed.  But,existing traffic policy seems missing port option.
Please help out and thanks very much.
