Martin Grigorov commented on WICKET-4591:
-----------------------------------------
64 components in a page is a quite small number.
Usually pages have few hundreds components and I haven't noticed such slowness.
Can you attach a quickstart that demonstrates this perf issue ?
> Significant performance overhead encountered on wicket page with 64 components

> Key: WICKET-4591
> URL: https://issues.apache.org/jira/browse/WICKET-4591
> Project: Wicket
> Issue Type: Bug
> Affects Versions: 1.4.19
> Environment: Windows Server 2008, JDK 1.6
> Reporter: Irena Shaigorodsky
>
> A custom page totals 64 component render calls. The page takes 10138 ms to
> open as profiled with Java Profiler for Eclipse.
> Following hot spots were identified by profiler:
> org.apache.wicket.proxy.LazyInitProxyFactory$JdkHandler.invoke() 3208ms
> 9 calls 356 ms/call
> org.apache.wicket.util.resource.locator.ResourceStreamLocator.getResourceStream()
> 2891ms 52 calls 55 ms/call
> org.apache.wicket.util.resource.locator.LocaleResourceNameIterator.next()
> 1310ms 24 calls 54.58 ms/call
> org.apache.wicket.util.file.WebApplicationPath.find() 1167ms 16 calls
> 72.94 ms/call
> org.apache.wicket.util.io.IObjectStreamFactory$DefaultObjectStreamFactory$2.writeObjectOverride()
> 306ms 2 calls 153ms/call
> org.apache.wicket.Component.writeObject() 255ms 4 calls 63.75ms/call
> org.apache.wicket.util.resource.locator.ResourceStreamLocator.locateByClassLoader()
> 118ms 54 calls 2.18 ms/call
> Totaling 9255 ms spent in Wicket code and unacceptable performance. Can
> Wicket support custom pages of that size? How the performance can be improved?
