| Subject: | 1.4.5 gnu sort 2.0.16 extremely slow under Win98 (tiny default buffer) |
| Note-from-DJ: | This may be spam |
I looked at the temp files sort creates and noticed that they were around
700 bytes (bytes, not kilobytes) in size. The normal behavior of sort is to
create temp files of around 16kB in size.
When I use the --buffer-size option to force a large buffer,
like --buffer-size=200000 (200MB) sort completes in seconds.
I'm running sort like this:
cat <47k line file> | perl -ne "<script that returns 1000 lines from the
source file>" | sort -k 1nr,1 -k 2,2 -o outputfile
The perl script on its own takes a second or less to run - it's a simple
filter.
