Have a look at htable.setScannerCaching, and please, please upgrade to 0.20 post haste. The only answer to 0.19 perf problems is "upgrade to 0.20"

My scan is taking about 6 seconds to do the following: 470 rows extracted total size of all rows together is about 1.4 megs I'm using a InclusiveStopRow filter to limit rows which are being extracted by the scanner. The problem for me is that I will soon be scanning 30x this amount of data soon, and 6x30 seconds will be quite a hit. We're already planning to jump to HBase v0.20 soon. But, wanted to see if folks thought the 6 second timing on this scan was reasonable, or horribly off. Thanks. Kyle
