gaaa! this also affects my recent performace numbers :-( I used direct read/write to /dev/mmcblk0p3 but this partition still was sync-mounted! after unmounting I get ~1.1 Mbyte/sec read: 1088 K 0.9355 0.9355 1190935 1120880 2112 K 1.8744 0.9389 1153796 1116793 3136 K 2.8341 0.9597 1133093 1092654 4160 K 3.7621 0.9281 1132293 1129850 5184 K 4.7092 0.9470 1127252 1107226 ~1.4 Mbyte/sec write: 78912 K 52.9782 0.2834 1525267 3699933 79936 K 57.8466 4.8685 1415025 215381 80960 K 58.0113 0.1647 1429083 6367664 81984 K 58.2917 0.2804 1440198 3739745 83008 K 58.6144 0.3227 1450158 3249453 but it's still worse than in August, and enable/disable "sd_idleclk" doesn'tseem to make any difference...
