ruby on rails - Is there a drop-in replacement for ActiveRecord to_xml that's faster? -

-

I have a large array of ActiveRecord objects (~ 400 elements) that I have to convert to XML. I've used array.to_xml for convenience, but it is very slow - the server is busy for 20 seconds, and about 5 seconds when idle.

I was just a server passive, and found that:

  • The ActiveRecord query (with two-level completions included) is approximately 0.3 on average.
  • To convert, the approximate results on XML takes approximately 4.9 s. 4.86 s user CPU time out of that.

Is the builder :: XML drop-in replacement for markup that will improve the speed of the two-XML? Or do I have to roll in some hands?

The following link claims to be a 2 - 3x speed increase. It is not a drop in substitution, but it is a technique that uses to create the structure that the two-XML will move faster.

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
