What actions do you need to undertake from the WKB byte array that cannot be taken using the IGeometry interface?

What is the correct/fastest way to convert from Fgf to Wkb?
I am using the FDO from .Net.
Currently I'm doing it this way:
byte fgfBytes = reader.GetGeometry(p.Name);
using (FgfGeometryFactory gf = new FgfGeometryFactory())
using(IGeometry geom = gf.CreateGeometryFromFgf(fgfBytes))
byte wkbBytes = gf.GetWkb(geom);
// Do some stuff with the WKB array
For some rather large MultiLineString geometries this takes incredibly long
time, specially the GetWkb function. E.g. one geometry concisting of 1500 kB
data takes about 10 seconds. (I have a rather fast computer...)
Is this the correct way to create a Wkb from Fgf?
