Hi
I'm testing the ARCHIVE storage engine and i vase some performance problems...

Test table consist of 30 columns:
- 1 blob,
- 1 bigint (primary index),
- 24 int,
- 1 datetime,
- 3 float.

Currently I've got 13000000 records inside, they use 13GB on MyISAM and only 3GB on ARCHIVE.

When i was testing random selects from this table I've got results on selecting 1 row:
MyISAM : 25ms average
ARCHIVE: 47615ms average.

Am I doing something wrong or does ARCHIVE cannot search for given KEY and must read whole table?
