Subject Re: ActiveMQ v5.0.0 Performance issue
Date Fri, 21 Dec 2007 07:25:33 GMT
Although syncOnWrite will be slow - I think the size of the data logs  
- 1000mb is very large. Its is possible that syncOnWrite will provide  
acceptable performance for smaller data log size - have you tried it  
with the default size ?
