Hi Siva, Summary: UEFI HTTP: 2.35 Mbps Windows wget: 14.1 Mbps
Could you clarify whether in the LAN scenario you get 100 Megabytes or Megabits per second? If you are getting 100 MB/s (instead of 100 Mb/s), I would like to follow up on how did you achieve such speeds :) If it's 100 Mbps, this sounds to be pretty slow for current UEFI network stack, knowing it can do ~550 Mbps when doing PXE boot with WDS server set on LAN (so network stack up to UDP seems to be working at least this fast). In case of HTTP boot, there is TcpDxe <-> HttpDxe <-> HttpBootDxe path that would have to be checked for bottlenecks. Thanks!

There was a HTTP server running in California and when an 450 MB ISO tried to downloaded from that below are the time took to download. The data retroeived with the same Platform and same controller. UEFI HTTP: 1529 seconds 310128 Bytes/seconds Windows wget: 255 seconds 1859551 Bytes/seconds The performance is still high (over 100MB/s) if the server is in LAN. When we tried to change MNP_SYS_POLL_INTERVAL from (10 * TICKS_PER_MS) to (5 * TICKS_PER_MS) it does not give big change in download time. Is there any other way to increase the speed or its limitation due to the single threaded execution. -Siva -------------------------------------------------------------------- Intel Technology Poland sp. z o.o. ul.
