Re: TWO LINE PATCH, SPEED UP 2 TIMES

[[EMAIL PROTECTED]]

Sorry for been repetivie, but here is another patch to increase the 
speedup a little(not us big as the first one but significant).
It seems that create a CacheXPathAPI is a really expensive operation, 
and it's better to postpone it till if it's ever needed.

Please test it.

Thanks.
