My main test machine is a fairly normal Micron 166Mhz Pentium with NT 4.0 server and Windows 95 installed. It has 32 MB of RAM which isn't a completely obscene amount these days. I see a definite speed-up in compile times and usage of the various tools feels snappier. I should actually measure the time to do configures under b17 and 18 at some point but it certainly isn't taking 16 seconds to do an 'ls' of a fairly empty directory for me. The cygwin.dll in beta 18 does use more RAM, so it could be that the dll is being swapped in and out of memory. At the risk of getting hundreds of replies :-), those of you who are seeing the slow-down: 1) Are you running NT or Win 95? 2) How much RAM? 3) Are you using memory for other open applications when you see the poor performance? If so, does cygwin performance increase when you quit those apps? Please reply to me directly. I'll post a summary on the list.
