Re: 8 hours tests ends with inconsistent DB.

[Trevor Warren <trevorwarren@yahoo.com>]

Hello Quanah,

 I totally agree with you on the same. Infact this is
the norm for all the performance tests carried out by
us for any system under test.

 We started out with 1 Lakh records and are still at
one lakh since the god damn thing manages to go down
at the drop of a hat.

 I just ended an 8 hour test on my HP DL580 G1
4cpu-4Gb machine for 200 users with think time.
Writes/s are 28 but the server aborted with the same
malloc error as in yesterdays overnite test.

 Qunanh.....all said and done unless this setup can
scale atleast for 1 Lakh users i can't recommend it
for my setups across 50 countries across the world.
More importantly i am very interested ni seeing Open
Source scale. 

 I humbly hope my feedback is helping developers
understand issues and scale the app by elimnation of
the code bottlenecks as soon as possible.

 BTW: My aim was to get to 50million users...:D. Its
one of the largest systems worldwide we would have
ever built if we ever did.
