SDO upload times

[flosse]

I'm curious to understand why reading a SDO takes 25ms in operation mode whereas with the SOEM stack it takes only 2ms. Do you have some experiences with this? Is this timing behavior caused by a bad configuration?

Here is my context:

• v1.5.2-sncn-11
• Ubuntu 18.04.4 LTS
• Kernel 4.19.118
• Intel Ethernet I218-LM / driver=e1000e
• Cycle Time: 1ms
• Slave: Weidmüller ur20 I/O system
