Nope. I doubt I did that, but even if I did, it couldn't explain the slowdown. Sometimes I needed to hold the netlist in memory (as a graph), and thus allocated space for every line anyways. (Actually, up to five times for each line: data structure, device name, source name, drain name, gate name.) Unless I ran out of memory, this never caused a significant slowdown.
