Thanks for reply! I'm running with single thread.
Actually I want to know: How really fast that HBase write can be with each thread? And how to optimize it? Config BLOCKSIZE/WriteBuffer ...? I'm a newbie. Thanks for help! jingych From: Asaf Mesika Date: 2013-11-26 19:20 To: [email protected]; jingych Subject: Re: How to improve the write performance? How many client threads?

I think the performance X-factor is : 1) client buffer size; 2) server memstore size; But when i did the test, I have the result is : 1) As the client buffer size increase with 2M, 4M, 8M, 16M, 32M, and the write speed is 320.4 331.4 336.4 343.2 371.7 （kb/s), it's 14columns into 1 column family. 2) As the server memstore size increased, the write speed is the same almost. This confuse me! I want to know: 1) What is the key factor influence with the client write performance? 2) How to improve the write performance? Thanks!
