you're sending a comma separated string to the server? why not have 2 hey digits for all the data and omit the comma? this would bring your data to 2/3 of its size, which means 26sec*2/3 = 17.3sec when this works, you could try to send binary data - so instead if sending the string "ff" you would send the binary byte 255. if this works, this would cut the time in half again => 8.6sec if you can't create binary data, you could still use base64 encoding instead, which would give you 8.6*1.33 = 11.5sec. regards Claudius _______________________________________________ Flashcoders mailing list Flashcoders@chattyfig.figleaf.com http://chattyfig.figleaf.com/mailman/listinfo/flashcoders
