Hi Angel,

 

 

Logging UDP syslog messages to a remote server should be fairly efficient and not add latency. I do think it's a blocking operation. But as it's UDP, TMM doesn't have to wait for the syslog server to respond to a connection attempt.

 

 

HSL is very efficient in terms of CPU and memory usage. So I'd recommend using it once you're on 10.1 or higher.
