I think I am also having the same problem. I already reported it to the
mailing list (Subject: Swiki with 2.5: Saving a page takes very long on
Netscape, see posting and answers below as a summary). I am not aware of any
fix for the problem.

I reproduced it on my machine at home with Squeak 2.5VM (release build 6)
from Sep. 6 1999 under Windows NT with service pack 4. I did the following:
I took a fresh 2.5 image and fetched the newest updates. (Squeak 2.5 of
August 6, 1999, Last update: 1447)
I set up a Swiki called 'bp' using the instructions in PWS
class>>howToStart.
I started the PWS on port 8099. (netstat -a shows p166:8099 0.0.0.0:0
LISTENING) p166 is the name of my local machine.
I started Netscape Communicator 4.03 (German Version) on the same machine.
The settings are: Cache: Never, Proxies: Direct Internet Connection (No
proxies)
I entered the URL http://p166:8099/bp.1. The front page is shown without
delay.
I click Edit this page..., change the page and click Save.
Now it takes 45 seconds until the changed page is shown. In the meantime
netstat -a shows two additional TCP connections: p166:8099 P166:1069
TIME_WAIT and p166:8099 P166:1070 TIME_WAIT. It takes some minutes until the
connections disappear again.

I did some more testing and once there were more than 90 connections
waiting. The connections seem to go away when I close the browsers. The
delay always seems to be 45 seconds. It always happens when I save a page.
It also sometimes happens when I access the front page. I tested this by
continuously clicking Back to the Top. There is no delay when I save a page
with Internet Explorer 4.0.

I checked it again with Squeak 2.4 (Last update: 1155). There are also
waiting connections but there is no delay when saving a page with Netscape.

I don't know much about TCP/IP networking. So I have no idea how to solve
the problem. I am willing to do more tests if someone gives me some hints. I
appreciate any help.
