PRADO performance tuning for high-traffic web applications

[giavinh]

Hi all,

I saw this topic http://www.eioba.com/a77342/prado_performance_tuning_for_high_traffic_web_applications , I really like it but there are something unclear with me.

Can anybody give me more examples code about:

c) Set cache class   * * * * *

Don't generate all the data on every request. PRADO can save parsed templates, configurations etc. in cache. (can be enabled in application.xml)

d) Keep pagestate in your database  * * * *

PRADO pagestate can be really big – it’s about 10kb-100kb of data. And by default, you send this data on every AJAX request!  (just use TDatabasePageStatePersister class)

e) Sometimes it's better to set PostState of ActiveControl to false  *

If you have a control like TAutoSuggest, by setting this option, you prevent PRADO from gathering all fields on a form values, on every AJAX request. ( ActiveControl.ClientSide.PostState="false" )

Thank you so much,
Best Regards,

Not directly an answer to your question, but if you really care about performance, take a look a this post:

Im no expert but I think the following is correct

D) TdatabasePageStatePersitor inspired the module TCachePageStatePersister and by specifiyng a cache of database type you can implement the storage in database (or any other cache module). NOTE On MySql if you let the cache create the table it creates the field as a Blob object NOT a LONGBLOB there was a bug report on this that it has been fixed but it isnt in the current 3.1.1 release I spent the better part of a morning trying to figure this out, especially since it does not initially appear as being related. (The page state data gets added but when it is extracted a null is returned, of course this doesnt occur on all the serialized data just on large pages so tracking it down is a B****)

E) The attribute returns a TCallbackClientSide (Accessed by ClientSide.PostState="false") And the documentation is wrong for this class (The heading says the attribute is PostInputs, no such attribute exists but I assume Wei was talking about the PostState ?!?)

And C) has been answered.

Hope that helps
