PhpDumper and large strings

When the PhpDumper is dealing with longer strings, the regular expression performed to optimize this can be quite a performance hog.
In our case sometimes the dumper takes more then 30 seconds if leaving this enabled. Disabling it will bring it back to sub-second speed.

This patch makes the optimization optional by passing in an additional container option.

I don't like adding yet another option for something that should "just works". It would be better to find a better way to optimise the strings for all cases.

I never really tested how much of a runtime difference it incurs when either using the "optimized" version or the non optimized version, so:

Having an example at hand which generates stable results yields (in a non-debug environment with a booted container using either of the optimization methods):

Without optimized strings:

  95%     14
  98%     14
  99%     15
 100%     48 (longest request)
```

So the response times differ by around 0.8ms

Building the non-optimized container takes around 800ms
Building the optimized container takes 43 seconds

From my Point of View it would just be viable to remove the optimization (since it already incurred some issues fixed in 808088a3ca607bf62f6c70ef7d3a3066f0cfac98).

I do not see a way how to improve the regexps (but by all means I'm no regular expression guru)

---------------------------------------------------------------------------

I'm also for removing these optimizations. What others think?

---------------------------------------------------------------------------

by Baachi at 2012-08-30T07:54:53Z

I'm +1 for removing this feature.
The performance boost is to small.

Can you add a note about it in the changelog of the component? thanks
