Q:

"Queueing" or "Queuing"

Which spelling is better, queueing or queuing? Both words seem to mean the same, but there are two different spellings. My context is:

Queueing Latency  

versus

Queuing Latency

If both spellings are applicable, when do I use which one of them?

A:

Just in case if anyone is wondering which one is more popular: (Queuing!)

A:

Both occur and there's no difference in meaning.
