The following figure shows the normal return result and the abnormal return result respectively

Performance of the LECPServer HTTP service

Test Equipment

1. CPU INTEL Core I7-1065G7 1.30Ghz processor
2. 16GB DDR4 RAM
3. SSD M2 disk
4. Windows10 Professional 1909 64bit Operating System
5. Schneider TM200CE24R PLC

Testing method

1. Set a BOOL point C0000 and a WORD point H0000 for the PLC, open 50 read threads and 50 write threads, run the plc_read_node and plc_write_node commands, and test the response speed of the two commands
2. Set a BOOL point C0000 and a WORD point H0000 for the PLC, open 50 read threads and 50 write threads, run the plc_read_nodes and plc_write_nodes commands, and test the response speed of the two commands

?> Conclusion, the first set of test results, 50 read threads and 50 write threads, the read and write return time for a single thread is 10ms-13ms, the second set of test results, 50 read threads and 50 write threads, for a single read Write return time is 20ms-24ms
