Does it use a ThreadLocal for the FieldsReader? If so, that is somewhat less efficient (than using a ThreadLocal on the streams in the FieldsReader - as the modified code I supplied does).
In either case it is better than the synchronization on the document() call. It is just not needed. -----Original Message----- From: Grant Ingersoll [mailto:[EMAIL PROTECTED] Sent: Wednesday, May 17, 2006 7:29 PM To: java-dev@lucene.apache.org Subject: Re: FieldsReader synchronized access vs. ThreadLocal ? Somewhat related, the Lazy Field loading patch uses a ThreadLocal on the FieldsReader to handle. It is issue 545 in Jira.
