Slow Download Speeds - Nav2013 Web Services

Nullsig

We are working on an implementation of Navision's Web Services using PHP. The code works for all intents an purposes but the execution times are unwieldy.

To do a single record read the process takes about 4 seconds. Almost all of that time is in the download of the response. Normally I would assume this has to do with ISP limits, but this is two servers on the same network with a gigabit switch and the response is only 5.5kb

Here is what I see when I pull the cURL info from the call:
array(26) {
["url"]=> string(70) "<Web Service URL>"
["content_type"]=> string(23) "text/xml; charset=utf-8"
["http_code"]=> int(200)
["header_size"]=> int(685)
["request_size"]=> int(1109)
["filetime"]=> int(-1)
["ssl_verify_result"]=> int(0)
["redirect_count"]=> int(1)
["total_time"]=> float(3.342556)
["namelookup_time"]=> float(1.0E-5)
["connect_time"]=> float(1.0E-5)
["pretransfer_time"]=> float(6.9E-5)
["size_upload"]=> float(269)
["size_download"]=> float(5448)
["speed_download"]=> float(1629)
["speed_upload"]=> float(80)
["download_content_length"]=> float(5448)
["upload_content_length"]=> float(269)
["starttransfer_time"]=> float(3.341836)
["redirect_time"]=> float(0.000706)
["certinfo"]=> array(0) { } ["primary_ip"]=> string(11) "<ip>" ["primary_port"]=> int(8047) ["local_ip"]=> string(12) "<other ip>" ["local_port"]=> int(60487) ["redirect_url"]=> string(0) "" }
