New to ignition so please be kind. The system has been running for several months and about a month ago production has reported that the system is "slow" and that the clients "freeze" and must be re-started at least daily. I did not design the system, it was done by an engineering firm that no longer works for us. Below are the details that I have gathered: 1. Number of device connections : 6 (Allen Bradley L8x PLC's) 2. Number of Tags : 162,843 3. Frequency of tag polling : 5 second (I have tried lowering this but when I do the device aggregate statistics "overload" increases from 1% to 85%) 4. Number of concurrent clients : 4 (except when troubleshooting and at that time I will launch a client so I can observe) In terms of architecture we are running a primary server, a backup server and a historical. All servers are Dell PowerEdge R340 with Intel Xeon CPU @ 3.70 and 32 GB RAM. Server resource monitor shows CPU usage to be around 1% usage and memory around 80% max. Thoughts on improving performance and reliability? ---

1. That's a painful load situation for a reasonable number of tags. You should study this topic and some of the links therein: > [@Cannot read some tags inside Rockwell AOI](https://forum.inductiveautomation.com/t/cannot-read-some-tags-inside-rockwell-aoi/38393): > > I am trying to see tags inside an AOI. I went back to basics and dragged and dropped the tags from the OPC browser into the Tags Folder, but the quality is bad and there is a red x next to them. What is more confusing is that some are working and some are not. I cannot see any similarities between the few that aren’t working. Data type, In and Out types are working and not working. I can create a new UDT as an In/Out but this seems cumbersome. In this case, I would need to create tags only fo… You may also find this topic helpful: > [@Automation Professionals' EtherNet/IP Communication Suite V2](https://forum.inductiveautomation.com/t/automation-professionals-ethernet-ip-communication-suite-v2/68190): > > Automation Professionals is pleased to announce its latest EtherNet/IP Communications Suite driver module, a major upgrade to its EtherNet/IP Class1 Communications module, as a Public Beta.

That is much more trouble to find and fix--possibly requiring some redesign.
