Is the Prusa Mk3 quite a slow printer?
I'm loving the printer but I'm noticing it is quite slow compared to many of the file descriptions on Thingiverse and the like.
For example, this platform jack: https://www.thingiverse.com/thing:925556
At 0.2 layer height on Slic3r Prusa Edition the GCode with the latest drivers on standard Prusa PLA settings work out to 10 hours 15 minutes
The description of the STL says the following:
The updated model was printed in 4 hours on a Replicator 2 with a 0.3mm layer height and 15% infill.
Even manually changing the layer height to 0.3 height since the option was removed gets the time down to 7 hours42 minutes
Is the Prusa 50% slower than a Replicator 2?

The MK3 to me is fast compared to my K8400 Velleman Vertex, especially on infill speeds. I heard that the 0.35mm layer height setting may be taken out of Slic3r for the MK3 as it would be rather pointless, as the 0.2mm setting pretty much maxed out the flow rate of the E3Dv6 0.4mm nozzle.
From the man himself explaing why. I think the only way to get more from the machine is to use an E3D volcano if you fancy modding things 😀

Could it be that Linear Advance is currently disabled?
It's quite a long, rectangular print.

Slower than a Replicator 2? Not a chance in hell. This thing's easily one of the fastest cartesian printers out there, and even gets close to many of the delta printers. There's likely a different explanation: the dude lied/was mistaken, he printed it at smaller scale, he used different settings, or something similar.
Keep in mind, the default profiles that Prusa provides are intended to provide a good mix of quality and speed, they are not intended to provide maximum speed. You can easily bump up the speeds in the settings if you care more about the speed than the quality. Acceleration will improve the speed dramatically. Note that depending on the settings you modify, the estimated time may not be accurate, you'll have to actually print it.
(Also, you should turn off the raft unless you have a really good reason for needing it, it wastes filament, ruins surface finish, and is slower.)
