Tf_prefix delays

Hi,
Does adding a tf_prefix causes additional delay? Below are the tf_monitor output with and without the tf_prefix rosobot1. I can find a good amount of delay when used with tf_prefix for baselink. When I try navigation the system without prefix performs better.

May I know if this is the sole reason or there could be other reasons too. Thanks.

Hi thiaga,

I’ve check delays before and after adding tf_prefix and they are almost the same (not like in your case). May I ask you to share with me the way you did that? It could help to fix the issue.

Best regards,
