parsing json, xml, gml can take a lot of time and costs performance.
after testing a lot we send our data this way:
the split function is very fast. splitting needs 1-2ms, parsing x00 to x000
that is the fastest method. no standard , but fast ;-)
an other advantage is less (50-80%) data (no tags, only a #)
500 poly with 15.000 - 25.000 Points are no problem.
a server side optimization is storing all values in an extra text field
so you dont need to concat the values. one "echo" is enough. no standard,
but fast ;-)
i figured the idea out after reading the articel below-mentioned
