I'm reading a book about Distributed Systems (Computer Engineering).

I faced with following context :

Full transparency will cost performance, exposing distribution of the system

What does "Cost" mean?

    It will influence the performance in a negative way - It will cost you some performance – mplungjan Apr 29 '14 at 12:06

    cost v.tr. 2. To cause to lose, suffer, or sacrifice: Participating in the strike cost me my job. thefreedictionary.com/cost – Kris Apr 29 '14 at 12:49

Full transparency will negatively impact performance. It is an example of "you can't get something for nothing."

The writer could also have used "decrease performance" or "reduce performance" or "degrade performance", but using "cost" is an allusion to the concept of Cost / Benefit trade-off.
