Slow Performance

[sherm4n]

Hi

Any tricks/hidden parameters i can use to make NNA to run faster
We found NNA takes too long to display Top 5 list, almost 1 mins, a simple query search dst port = 53, takes forever to return.
The box we used for NNA evaluation is HP DL360 G7 with 8 cores E5506 CPU, 24G Ram.

The same box to run NetFlow Analyzer from ManageEngine without any major delay like NNA

Any suggestion we could try would be welcome.

Regards
Sherman

The largest bottleneck in Network Analyzer is going to be the disks and the time period you are running the search over.

To process all of the data, the netflow data is read from disk.
Do you have a fast disk array or SSD drives in your Network Analyzer machine?

If you chose carefully from here, and try stuff slowly, piece by piece, you may get some satisfaction with the speed issue.

The default of 24 hours for all the views kills me too. I kept track of all the little things I have done to make my stuff run faster.

Just look at the gui improvement pieces. Each one stands alone. Decide what you are willing to touch. These are what I have done to make things a little better for me.

I suggest skipping the nfdump wrapper part. Up to you. I use it. I wrote it.

We all hope that the new version of NNA performs better. Just use this to get you thru for now.
