gotcha. that does sound strange. I just wrote a little program to test that and found out that's also true for Windowz. no probs reading same file simultaneously using two BufferedInputStream objects. strange, huh? zm.

I mean, if that were true, then there would be no way to fix it by using a "non-synchronized" BufferedInputStream, right? And anyway, he said he was using Linux on a x86 box. I use Linux as one of my dev platforms, and unless he's using some really bizarre JVM, then I can guarantee you it doesn't work that way. I suspect he was hitting random variations in how his threads were getting scheduled, resulting in one thread briefly getting most of the bandwidth. Or maybe they were running one set of tests with native threads, and another with green threads. There's not really enough data to draw a conclusion. But it wasn't a problem with BufferedInputStream. -- Christopher St. John [EMAIL PROTECTED] DistribuTopia http://www.distributopia.com =========================================================================== To unsubscribe: mailto [EMAIL PROTECTED] with body: "signoff JSP-INTEREST".
