If your source file for the ePUB is a single 170MB HTML file, then the ePub will not work on many readers. The problme is that it will get stored as one large compressed chunk, and need to be completely decompressed to read it.

Mobipocket format automatically splits the file into chunks to be compressed, and only the current bit needs decompressing, so reading is quite quick.

You could try splitting the file up into lots of smaller HTML files (under 300KB I think is the reocmmended size for greatest compatibility). This should greatly reduce the time taken to open and display the epub.
