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


Queuing Latency

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

    The shorter spelling has rapidly taken the ascendancy in recent decades, and I don't think this is particularly a US or UK thing, so I'd advise going with it if you want to seem more up-to-date. Commented Mar 12, 2012 at 13:13

    You have to use Queueing as it is the word with the longest consecutive use of vowels.

    The longer form is preferred.

    At MIT, I was taught that the MIT spelling is "queueing"---after all who can resist a word with five vowels in a row.

Both occur and there's no difference in meaning.

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

    ty for your work (i've +1-ed it), any idea if we could expand the end date? for me it seems to display 2008.

    @p1100i the Google Ngram viewer (which was used to generate the graph; reproduce it here) currently only shows data up to 2008.
