Out of curiosity,  could you be running into a common problem with DNS lookups and IPv6? Try using the IP address or disabling IPv6.

Subject: [Seaside] Page Load Time

 

Below are the results for load time of Google’s home page and my simple “Hello World” application:

 

Google home page

10 requests  ❘  20.01KB transferred  ❘  371ms (onload: 314ms,

DOMContentLoaded: 123ms)

 

Seaside “Hello World” application

2 requests  ❘  4.86KB transferred  ❘  1.03s (onload: 1.05s,

DOMContentLoaded: 1.05s)

 

I used Google Chrome to measure the results.

 

My “Hello World” application simply displays “Hello World” as H1, nothing more. I use the default Seaside setup, with a the browser running locally.

 

I run Pharo 1.2.1 and Seaside 3.0.3.1 on a powerful (8 GB Ram, SSD disk, Intel i5 661 CPU) Windows 7 64 bit box.

 

Google’s page is minimalistic; a typical page uses a few seconds to load. Still, wouldn’t you expect the minimum load time to be far less than 1 second?

 

I perfectly well understand that minimum load time does not say anything about the load time for a more complex page.

 

Kind regards

Runar
