Date: Thu, 30 May 2002 19:06:06 +0000 Mime-Version: 1.0 Content-Type: text/plain; format=flowed Message-ID: X-OriginalArrivalTime: 30 May 2002 19:06:07.0202 (UTC) FILETIME=[0D638C20:01C2080D] Larry, The issue is that strace output is too voluminous and os too intrusive. strace itself brings down the performance of the server I built. I tried a Dec 2001 pckage of cygwin and got the same results, so my guess is that the problem manifested itself somewhere b/w Dec 2000 and Dec 2001. Are there ftp archives of the older packages I can try. Please help me out here as I have really bad deadlines that I have too meet :) THanks -Johnny >From: "Larry Hall (RFK Partners, Inc)" >To: "Johnny D" , cygwin AT cygwin DOT com >Subject: Re: Big Performance issue with CYGWIN 1.3.10 on Win2k - Urgent >help reqd! >Date: Thu, 30 May 2002 10:18:51 -0400 > >At 11:42 PM 5/29/2002, Johnny D wrote: > > >I am not sure when this bug might have been introduced.
