#1 amazingly slow for 1MByte files

[mkbane]

I've 2 files, both I believe valid ncf files, with a single variable x of about 1000 elements. nccmp has been running for 11 mins and not yet reported that there's any diff even though I know the 12th element differs...

Files attached

Please advise, M

It seems that putting values in for -t forces it to give some results (why is this required?), but despite outputting the values for elements close to the end it apparently never gets there...

Actually, I'd have to say I've given up with nccmp and gone with the NCO option which appears to be fast and does the job I required.

Thanks

My apologies. This was filtered by my email client long ago. 2GB files compare in 15 seconds on my desktop, and 10 milliseconds for your attachments. The first value is different (19,137 actually), shown in hex too.
