Extremely slow connection on local network (Zope 2.2.5, Win2k)
Hi, folks-- I'm trying to set up a Zope-based intranet web site for my company, but there's a very puzzling performance issue. Basically, any attempt to connect to the server from another machine on the local network is really, really slow: for example, I just visited the default home page (the "Welcome to Zope" page that comes w/ the installation), and it took 25 seconds to load. More complex pages can take over a minute. I don't think Zope itself is running slowly, because if I log onto the server and access the site locally, it pops right up. I'm also running IIS on the same machine, and have no trouble accessing the IIS website from various hosts (I did make sure they weren't trying to use the same port -- Zope is on 8080, IIS is on 9680). Here's some info about the environment: Server Platform: ---------------- OS: Windows 2000 Professional w/ Service Pack 1 (installed w/ Norton Ghost) Hardware: Celeron 600 Mhz, 160MB RAM Quirks: I added PyXML and ReportLab to <zope_dir>\lib\python. I also added an external path with some other python packages to sys.path in z2.py. There is a separate Python 1.5.2 installation on the machine. Network: -------- Type: Ethernet 10-base-T, single subnet Router: FlowPoint DSL OSs: Mainly Windows 2000, with one Solaris box and a small but varying number of Linux, NT 4.0, and Win98 boxes. Domain Controllers (2): Windows 2000 Server running in mixed mode By the way, we have frequent performance problems with the network, but nothing nearly as severe as this. We suspect that not having enuf client licenses for Win2k Server may be part of the problem, but I don't see why that would affect Zope, especially since IIS seems to be fine. I would greatly appreciate any suggestions you may have. -- Matt Gushee Consultant Architag International 6989 South Jordan Road, Suite 6 Englewood, CO 80112 Phone: 303.766.1336, x124 Cell: 303.941.0759 Fax: 303.699.8331 E-Mail: mgushee@architag.com Web: http://architag.com
If you visit localhost via the IP address (127.0.0.1), do you experience the same problem? ----- Original Message ----- From: "Matt Gushee" <mgushee@architag.com> To: <zope@zope.org> Sent: Wednesday, January 31, 2001 3:16 PM Subject: [Zope] Extremely slow connection on local network (Zope 2.2.5, Win2k)

Nope. When I'm sitting in front of the server, the connection is equally fast whether I use the actual host name, 'localhost', 127.0.0.1, or the external IP address (which is assigned by DHCP, by the way). Similarly, from a remote host, the connection is equally slow whether I use the bare or qualified hostname, or the IP address.

Hmmm. I have a feeling that this may be related to a DNS lookup problem in user folders that was solved in Zope 2.3. Is it feasible for you to try 2.3? ----- Original Message ----- From: "Matt Gushee" <mgushee@architag.com> To: "Chris McDonough" <chrism@digicool.com> Cc: <zope@zope.org> Sent: Wednesday, January 31, 2001 3:52 PM Subject: Re: [Zope] Extremely slow connection on local network (Zope 2.2.5, Win2k)

Okay, I'll try that. Hope it doesn't break all my applications. Thanks. I'll let you know what happens. -- Matt Gushee Consultant Architag International 6989 South Jordan Road, Suite 6 Englewood, CO 80112 Phone: 303.766.1336, x124 Cell: 303.941.0759 Fax: 303.699.8331 E-Mail: mgushee@architag.com Web: http://architag.com
