I think we need to brainstorm on this. What are the other ways that we can handle this? What are the implications , if we put a size limit on the contents file and when it reaches the max_size, open a second file. How does other OSes handle this? Having a huge file is a problem and as time goes, the problem only increases and performance can only decrease. So, we must look at this very seriously and search for better alternatives. -Narendra -- > Bart Smaalders Solaris Kernel Performance > barts at cyber.eng.sun.com http://blogs.sun.com/barts > _______________________________________________ > install-discuss mailing list > install-discuss at opensolaris.org > http://opensolaris.org/mailman/listinfo/install-discuss > -- Warm Regards, Narendra Visit my blogs at: http://ssnarendrakumar.blogspot.com/ http://blogs.sun.com/roller/page/ssnkumar ___ ___ __ _ / __/ / __/ / | / / _\ \ _ \ \ / /| |/ / \___/ \___/ /_/ |__/ -------------- next part -------------- An HTML attachment was scrubbed...
