Thanks, Ingo.
We have set the JAVA_OPTs to set the Java VM memory, but it seems doesn't
work. As you said the problem might depend on the store implementation we
are using. Would you mind to tell me what does it mean of store
implementation? I am sorry that i am quite new to Slide. Thanks.
Also i have tried to print out the stack trace as follows, do you have any
ideas on it? Regards, Priscilla

Subject: Re: Performance issue of web application using slide
Hi Priscilla,
we are running Slide with an even larger user base without significant
performance problems. But that might depend on the store
implementation you are using.
Concerning the memory problems you should make sure to give your Java
VM enough memory with the -mx and propably the -ms switches.
Regards,
Ingo
