Oops. Just saw the typo: should have been 16 flushers. This was brought to my attention by Chris Macadam with whom I'm speaking now. He has some other ideas about monitoring memory and specifically buffers. We'll get more detail on that and one of us will post that later. I'm glad Chris chimed in because his Linux knowledge is deeper than mine (I'm a Windows and Toolkit guy), and he is a LOT more familiar with your specific system than all of the rest of us in Support combined.

This flushers has impact over the backup too ? mine is taking to long time

So the backup is slow? I'm not sure what the flushers would have to do with that. Is the system live yet? If not, try reducing the flushers to 4 and try the backup again, see if it speeds up or continues to be slow. I'm not sure what CPU availability has to do with our file-save procedure, but maybe Chris does. I'll ask.

Hi Alberto,
Here is a link to an article related to tuning the number of flushers on a D3/Linux 64 bit system using more than 3.5GB of memory.
https://my.rocketsoftware.com/RocketCommunity/s/article/Tuning-the-number-of-flusher-processes-for-64-bit-D3-AIX-and-D3-Linux
In addition to this article, the 'd3 -qf' command is also helpful as it will show how much work each flusher is actually doing. If you have configured your system to use 16 flushers and the 'd3 -qf' command only shows 10 flushers doing any work then it's pretty safe to reduce the number of flushers to 10. The key here is that you want to do this after your system has been running for a while and has gone through some busy cycles so you get an accurate reading before making any change.
About the backup, are you saying that you changed the number of flushers and that impacted the speed of the backup? Or are you asking if having more than one flusher slows down the backup in general?
