Matthieu Baechler commented on JAMES-1635:
------------------------------------------
Let throw some figures : on our CI server, the timings for cassandra related
maven tasks are :
[INFO] Apache James :: Mailbox :: Cassandra ............... SUCCESS [08:02 min]
[INFO] Apache James MPT Imap Mailbox - Cassandra .......... SUCCESS [12:15 min]
[INFO] Apache James :: Server :: Data :: Cassandra Persistence SUCCESS [ 48.700
s]
It's why we set timeout to 30 minutes, it's about 3 times the longer test suite
execution time.
I understand that it can be slower on older/slower hardware and we can change
this value to 3600.
What times do you experience on your hardware ?
About the suggested solution :
1/ using a new keyspace for each test : I tried this one, it's at least 3 times
slower than wiping tables, it looks like table creation is rather slow on
Cassandra
2/ use parallel execution : it will load your hardware even harder, It can help
on multicore + SSD, but I'm not sure it will help on older hardware, and it
needs 1/ to work.
3/ remove some MPT tests : it's probably something to investigate
About total execution time, we have 35:32 min on our hardware, it's slow but
it's not 2h+
