[Biojava-l] RichSequence.IOTools performance

[Richard Holland]

I would have thought 10,000 seqs written out in full Genbank format in 20 seconds was pretty good! However, the key to speeding it up would be to modify the OutputStream interactions to use faster things such as NIO. Also it would depend on the source of your sequence objects - if they are all in-memory then this isn't an issue, but if they are being read from a database using lazy or dynamic loading then that could be a bottleneck too.
