Hi All,

The PIPE VMC stage apparently has a fixed 8K buffer, though I don’t know for 
sure if that limit is in the VMC stage or a limit in the Performance toolkit. 
When retrieving data it only returns 101 records of 80 bytes as 101 records 
fills that 8K buffer.

When I run PIPE VMC USER with more than 100 users in z/VM it will discard the 
last records. And in our CPC we have a number of LPARs, with multiple CPUs, so 
PIPE VMC LPAR also discards the records after record 101.

Is there a way to increase the buffer size, perhaps similar to the buffer size 
of the CP stage?

Met vriendelijke groet/With kind regards/Mit freundlichen Grüßen,
