Chris, As you pointed out, performance is based in many factors. The retrieval portlet content is one. Another is related to how fast the browser can render the returned page. Netscape 4.7x has a known performance problem with nested tables. Jetspeed uses nested tables :(
10 second is a long time to display the Jetspeed home page. I am not seeing this. Most of the time Jetspeed's home page is displayed in <1 second. By the way, thank you for quantifying "slow performance" !! Places to look: o Log files! Including Jetspeed's, Tomcat's, and the web server's. o General performance on the server machine(s), i.e. if server is low on memory it will spend a lot of time swapping pages instead of running applications. o Load and configuration on the client machine, i.e. is the client a 100 MHz PII with 16 MB of memory? o Proxies, the lurk on corporate networks and can cause caching and performance problems :( o Firewalls can prevent prevent content retrieval and cause jetspeed to wait for the request to time-out. o General network performance Paul Spencer Christoph Steinbeck wrote: > Hi everybody, > > I must say that this latest release of Jetspeed-1.3a2 is a great > achievement.
