Subject [jira] Commented: (SANDBOX-166) Improve memory use
Date Thu, 10 Aug 2006 04:57:14 GMT

Henri Yandell commented on SANDBOX-166:

Looks good to me. I think we'll want to attack the CharBuffer class for bugs a bit as it's
at the heart of the system, and it might be valuable for Lang (or there might be something
already in there that does the same thing); but the looking at the patch all the changes look

Do you want to go ahead and do the commits Ortwin?

You'll find that I accidentally committed the CsvUtils class before realising that I really
should be leaving it for you to do the commit - sorry about that.

> The parser is currently a real memory burner. I fed it a 4MB CSV file and ran the TPTP
profiler.  As you can see the parser creates around 100MB of garbage whereas it could (in
really optimized) use around 4MBs.  Such figures are not acceptable within a server environment.
