I have both a PC and Mac environment setup to connect to the same Oracle server. Both are using Oracle instant client and are on the same network. Both machines are similarly configured (e.g., 16GB, flash drive, network connections, etc.).

When I try to execute a select from a relatively small table using SQLPlus, it takes ~2ms on my PC while it takes over 2 seconds on my Mac. I've attempted to dig into the differences using the Oracle trace files and other tools, but have not found anything that I am doing incorrectly.

Google searches have not yielded any helpful results. Is this just a dead end for me?
