Are there guidelines for tuning the network parameters for a Linux host running a bunch of EPICS soft IOCs? We were seeing some issues with CA clients seeing delays of over a second for ‘get' requests. Setting the values shown here:
seems to have improved things. But I don’t know if those numbers, which I got from a google search, are way too big, or not yet big enough or completely weird. Suggestions welcomed. Machine details:
Load average in the 3 to 4 range but CPU utilization as shown by ‘top’ showed at least 60% idle even when clients were experiencing the slow response. --
