Duet file upload speeds over web interface I did some measurements on file upload speeds using various SD cards and two firmware versions. Here are my results: Card Duet 0.8.5 Duet 0.8.5 Duet NG prototype 1.10+4-dc42 1.12a-dc42 1.12a 2Gb unbranded 93 235 577 2Gb Samsung 146 348 786 4Gb Kingston class 10 227 550 856 4Gb Sandisk class 4 430 783 840 16Gb Sandisk class 4 373 986 895 These figures demonstrate how much the upload speed depends on the SD card, and the effect of the improvements I made in release 1.12. There was some variability, so all speeds listed here are best of three uploading a 10Mb file. The 4Gb Sandisk card came from T3P3 and I believe it is the card they are currently shipping with Duet 0.8.5 boards. The 16Gb Sandisk card is this one [www.amazon.co.uk] and the 4Gb Kingston card is this one [www.amazon.co.uk]. Anyone who is getting better than 1Mb/sec on a 10Mb or larger file upload, please let us know! https://reprap.org/forum/read.php?416,664836,664836#msg-664836 Sat, 12 Sep 2026 01:18:39 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?416,664836,665550#msg-665550 Re: Duet file upload speeds over web interface https://reprap.org/forum/read.php?416,664836,665550#msg-665550 Gaou Duet Thu, 19 May 2016 05:47:44 -0400 https://reprap.org/forum/read.php?416,664836,665071#msg-665071 Re: Duet file upload speeds over web interface https://reprap.org/forum/read.php?416,664836,665071#msg-665071 dc42 Duet Wed, 18 May 2016 02:52:03 -0400 https://reprap.org/forum/read.php?416,664836,665013#msg-665013 Re: Duet file upload speeds over web interface https://reprap.org/forum/read.php?416,664836,665013#msg-665013 Bob64 Duet Tue, 17 May 2016 19:00:56 -0400 https://reprap.org/forum/read.php?416,664836,664853#msg-664853 Re: Duet file upload speeds over web interface https://reprap.org/forum/read.php?416,664836,664853#msg-664853
It has more than doubled the upload speed I was seeing with 1.09r which was the last version I had been using now on 1.12a.

Very impressed keep up the good work David??

Easily hitting the 950 Kib mark just take an ocasional Glitch which drops it down to the 880 sort of mark but it then recovers up again.]]> dougal1957 Duet Tue, 17 May 2016 12:01:50 -0400 https://reprap.org/forum/read.php?416,664836,664836#msg-664836 Duet file upload speeds over web interface https://reprap.org/forum/read.php?416,664836,664836#msg-664836
