For your speed test you may be able to tweak it more by experimenting with how high your device will let you increase MaxReadGroupSize. Also the beta version 3.99y has further improved performance of subscriptions.
I made some extra tests with changing the MaxReadGroupSize property:
- 5 => for 100 tags - 6~7 reads/sec for 200 tags - 4 reads/sec
- 10 => for 100 tags - 10 reads/sec for 200 tags - 8~9 reads/sec
- 20 => for 100 tags - 20 reads / sec for 200 tags - 18 reads/sec
- 25 => for 100 tags - 25 reads/sec for 200 tags - 22 reads / sec
- 30 => for 100 tags - 28~29 reads/sec for 200 tags - some tags could not read
- 50 => for 100 tags - some tags are very slow to refresh
So with my device and my computer, if I wanna read about 200 tags simultaneously, the best results were achieved with a MaxReadGroupSize property of 25.
I will try to migrate to the latest version.
