Says who? And slow to whom?

1 - Write correct code

2 - Use a profiler, if the code isn't fast enough for the use 
case being written for

3 - If desired use case isn't there, use the profiler information 
to improve the specific hotpaths in need of tuning.

I see too many people micro-optimize for nothing.
