Cache Max Size

Code Block
cacheMaxSize="1000000"

Tomcat caches static files in memory so that it can respond faster. The cache has a max. size to stop it taking up too much memory. PhixFlow's static files (things like icons) are collectively too large to fit in the default cacheMaxSize, so we set it to a size that can accommodate all PhixFlow's static files.

conf/server.xml: Connector settings

...

  • Use the required port number (port="8080"). Tomcat defaults to port 8080 for HTTP, but you may need to use a different port if you are running other web servers on the same host.
  • Enable compression (compression="on"). Compressing responses from the server is particularly important if you are going to access the PhixFlow server over a slow connection (e.g. a mobile data connection).

After editing, the <Connector/> block should look like this:

...

Remember to enable this port in the server’s firewall (if enabled).

Compression

Code Block
compression="on"

Turning compression on reduces the amount of data passed between a client (i.e. a web browser on someone's computer), so this setting should improve the performance of the PhixFlow front end, especially if users are going to access the front end over a slow connection.

web.xml: Session timeout

The default session timeout period is 30 minutes. We recommend that you You can change this to a longer different period , e.g. 12 hours (720 minutes) .by doing the following:
