Hi Nitesh,
Thanks for your reply, got it, my server has 128GB RAM and 1Gbps bandwidth in data center. In addition, I noticed that the fabric performance will drop drastically if my ip list over 5000 lines, fabric output was very slow at that moment, how to optimize it?
Best Regards,
Leon from smart phone

Hi,
Pool size depends on your central server bandwidth and ram usable. You can specify n no. of ips in list.
In my scenario I use pool size to be 300 when I just want to connect to servers and transfer files in kbs. I use 50 pool size when I have to transfer installation scripts which is of 950MB.
My server's upload speed is 320Mbps and has RAM of 256GB.
Hope you understood on which factors pool size depends now.
Thanks!

Subject: Hi there, two questions from newcomer.Dear Jeff and All,
This is Leon from Beijing, I already installed fabric for my Linux server on Sep 2nd, 2016 in order to manage over ten thousand infrastructure devices (such as the server, storage and switch….etc) by SSH protocol. Just two questions at this time:
1.) how many address@hidden(pool_size)” should I specify in fabfile.py and what is a proper value for this parameter?
2.) what is the maximum number of rows in ip address list?
The following is my environment information, just waiting for your suggestions. Thanks in advance.
