Subject Poor performance on small data set
Date Fri, 11 Mar 2011 16:24:36 GMT

I'm facing poor performance issue getting a simple row

Here is my dev env :

- Windows 7
- PHPCassa [PHP 5.3.5]
- Cassandra 0.7.3

CF :
create column family docs with comparator = 'UTF8Type' and column_type =
'Standard' and rows_cached=100000 and keys_cached=100000;

There is less than 1000 rows and i've got a 75-100ms to get one row by id
With memcached it's 2ms....

I don't know where is the problem. jvm ? cassandra ? phpcassa ?

What can i do to detect where is the problem ?

Thank you,


ps: phpcassa say to use C Extension (but cannot use this C Extension made
for linux on Windows) but i'm not sure the issue is coming from phpcassa
