Did that implementation affect the performance, or because I am just in the
test system, the memcache can not make good performance improvement when the
messages are only more than 100 thousands? I want to check the code of
memcache, on the other hand, is it comes from I putting the memcache on
the same server of yapache and mysql?<o:p></o:p></span></font></p>

Hi Mr. Wang:<br>
I am working in yahoo email group in CA. We are using memcache as
our cache solution.<br>
(My director saw you email and let me help, if you thank, thank
him:) )<br>
How to use memcache is critical in performance in our cache
solution. We tried different methods for using memcache, we made tradeoff
for best performance and implementation complexity. The lesson we learned is,
make correct data object granularity, both too small or big will hurt
performance. Performance stats for email requests can be hundreds of times
difference for correct and mis usage.<br>
Not sure if this can give you a clue for your implementation? I may
can help you in big picture level.<br>
Thanks.<br>
