Houdini -> Maya, faster than FBX-cache solution?

[xtimmyx]

I'm developing a hair dynamics simulation system within Houdini which imports guide curves from Maya, simulates them in Houdini and then spits them back to Maya cached.

However, in my not so successful stress test I did tonight, exporting an FBX with 3.000 curves with 9 points each, and 300 frames is not yet complete after 14 hours.

Cacheing the geometry in Houdiini to *.bgeo-files takes about a minute, and that stores more data than the cache files, so I don't see why it would have to take so long. And the same geometry exported from Maya is also significantly faster.

Is anybody aware of a way to get the curves from Houdini back to Maya in a more efficient way? Perhaps another cache system?

The topology and naming of the curves is the same, so preferable would be to only export the cache and apply it to the existing curves in Maya.
