Subject [jira] Commented: (LUCENE-2504) sorting performance regression
Date Tue, 14 Sep 2010 12:26:33 GMT


Robert Muir commented on LUCENE-2504:

Java (Oracle) really needs to do something to address this.

I think we all owe it to ourselves to stop equating java with Sun/Oracle, if Java 
stays with Oracle its pretty obvious the language (is) will die anyway.

I think this is a severe and growing problem for Lucene going forward
- our search performance is crucial and we can't risk hotspot
randomly, substantially slowing things down by alot.

While I agree at the moment we should make efforts to work around issues like this,
I don't think we should jump the gun and make real design/architectural
choices based on Oracle bugs.

Especially for trunk, by the time we release Lucene 4.0 some other company
will probably "own" Java anyway.

Not that we have a choice here... but I've often wondered whether .NET
has this same hotspot fickleness problem

.NET is not a choice but generating C/C++ code is?
