Description

In the files

./trinidad-1.2.14/trinidad-impl/src/main/java/org/apache/myfaces/trinidadinternal/image/cache/FileSystemImageCache.java line:955
./trinidad-1.2.14/trinidad-impl/src/main/java/org/apache/myfaces/trinidadinternal/image/painter/ImageUtils.java line:303

The buffer size is fixed as 1024 bytes. With the size of the data varies, the performance can be damaged a lot.

We need an appropriate buffer size which depends on the size of the data to be copied.

This is the same as the Appache Bug (https://issues.apache.org/bugzilla/show_bug.cgi?id=32546)
