Hi,  
When I use -l along with -pal then my application doesn’t receive the input.  
Command used:  
./sdkperf\_java.sh -cip=H:P -cp=A -cu=B -mr=1000 -mn=25000 -l -nagle -ptl=my/request/topic -stl=my/response/topic -prs=my/response/topic -pal=mybinary.message  
Since I wanted to use replyTo I used sdkperf\_java as suggested by @marc.dipasquale in a separate thread.  
Is this not supported or am I missing something ?

Hi,  
Can you try with -pfl (text message)? If your application receives that, but not -pal (binary message), then maybe the application is not coded to handle binary message.

Problem is to use -l (for latency measurement) with -pal. I am able to send messages successfully with -pal but -l and -pal don’t work together.

I used the -md to see the underlying data on screen.  
with -l, I see first row of binary data changed. May be the tool does some shifting

I suspect the tool adds timing information in the message in order to calculate latencies. That may be interfering with what your application is expecting in the message.

May be, haven’t been able to figure out how to get rid of it.
