hi , dear skywalking team

I tried to search keyword like performance or something like that to get the metrics for skywalking performance loss.

I'm curious how much performance will lost for some middleware like RPC like、mq like、sharding like middleware if we using skywalking and turn the SW_AGENT_SAMPLE to 100%.

I believe the skywalking team must collect the info like that, would you please share the info ?
or some other people could share the situaion in your company ?

thanks in advance

Officially we don't. In theory, all features have their cost for sure.
