Hi @ChristianHoltfurth > ,
sure I can try to share as many details as possible 
I use the sdkperf sdkperf-jms-8.4.9.27 which I downloaded from products.solace.com under the path products/10.17GA/Tools/sdkperf_jms/Current/8.4.9.27/
The SOLACE_VM_ARGS I am using before running the sdkperf are listed above. The parameters I use are the following for
Publishing (I replaced the actual values with placeholders <>):
./sdkperf_jms.sh -cip=smfs://<Broker#1>:55443 -ptl= -mn=1 -msa=100 -mt=persistent -cu=@ -cp= -jcf=
Subscribing (Again, placeholders for actual values):
./sdkperf_jms.sh -cip=smfs://<Broker#2>:55443 -sql= -md -cu=@ -cp= -jcf=
For this usecase I setup two new Brokers in Version 10.2.1.32.
Any specific information you need about the Bridge Setup ?
I tried to create a draw.io image of the setup I have. I use queues for the subscribtions, no direct message transfer. The bridge is setup as unidirectional - so only Broker#2 has established a connection to Broker#1.
The message transfer works as expected in the setup. So
sdkperf publish to a topic on Broker#1 On Broker#1 is the bridge queue which subscribes to this topic Message goes through the Bridge onto Broker #2 where a queue lives which subscribes to the topic sdkperf subscribes to this queue Greetings,
Jan-Filip.
