---------------------------------
Hi folks,
I'm running into a similar problem (HBASE-9811) and I got some interesting
testing figures (in that ticket). Briefly speaking, 1) I get similar
improvement when replace SEEK_NEXT_COL with SKIP and 2) the performance drops
greatly as we get more HFiles. So did your test case use only 1 HFile,
