In case of HTTP boot, there is TcpDxe <-> HttpDxe <-> HttpBootDxe path that would have to be checked for bottlenecks.<o:p></o:p> <o:p> </o:p> <div> <div style="border:none;border-bottom:solid windowtext 1.0pt;padding:0in 0in 1.0pt 0in"> Thanks!<o:p></o:p> </div> Maciej Rabeda<o:p></o:p> DCG CG ND SW ITP PreBoot Dev<o:p></o:p> </div> <o:p> </o:p> <div> <div style="border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in"> <a name="_____replyseparator"></a>From: <a href="mailto:devel@edk2.groups.io"> devel@edk2.groups.io</a> [<a href="mailto:devel@edk2.groups.io">mailto:devel@edk2.groups.io</a>] On Behalf Of Sivaraman Nainar Sent: Wednesday, April 24, 2019 12:36 To: <a href="mailto:devel@edk2.groups.io">devel@edk2.groups.io</a> Subject: [edk2-devel] reg: reg : HTTP Download Performance<o:p></o:p> </div> </div> <o:p> </o:p> Hello All:<o:p></o:p> <o:p> </o:p> Would like to clarify few information on the timings on the HTTP Boot / Download performed through Windows / Linux and UEFI HTTP Boot.<o:p></o:p> <o:p> </o:p> 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.
