Vincent,

Are you booting to mmc? I had the problem myself then I flashed fanoush's double mmc speed. That fix helped everything a whole lot. Thanks fanoush I have a 2 GB rs-mmc from TopRam I bought on Ebay so it may not be as good of quality as other cards but I definitely got the performance boost after the patch. If you are booting directly to flash it probably is your connection dropping.
