Long 10m/20m CAT5e vs 1m CAT5 cable. Which is better for performance?

Title says it all

If they both meed all the specs for Cat5 or better then there is no significant difference. The delay through an extra 19m of wire is about 62 nanoseconds ...

 

[USAFRet]

Assuming a properly constructed cable, zero performance difference.

Unless you are running a quantum experiment, ZERO difference.
