|Summary||0006011: [TNG] UNIX communicator performance issues|
|Description||A trained eye might notice the absolutely unacceptable, abysmal performance of this|
communicator considering it is using UDS (we should expect ~XGB/s!).
As it is not meant to be used productively (and can't really) this is not a blocker, but
still something worth investigating. I do not know if this was also the case for the old
|Tags||No tags attached.|
||This is also an issue for the TCP communicator. Maybe this is a general issue with MQ or TNG api.|
We now also have a UDP communicator which does no flow control (additional messages with (mock)transport).
It is now likely clear that something is wrong with the MQ (in general?).
For reference, current numbers:
* Size packet test done.
* 12798/12798 packets -- avg latency: 3148434 us
* Short size packet test done.
* 5000/5000 packets in 838528 us (745 KiB/s) -- avg latency: 409401 us
* Long size packet test done.
* 5000/5000 packets in 1717230 us (88 MiB/s) -- avg latency: 1034307 us
In HEAD performance is now increased drastically (but still not optimal).
Unix: Short ~5MB/s Long: ~300MB/s
TCP: Short ~4MB/s Long: ~200MB/s
UDP is currently not functional. The packet send logic is very inefficient and the test always fails.
||Note that the issue might actually be test design and lack of FC and not so much the communicator itself.|
