> Hi,
>
> We developed e-commerce site using WebSphere 3.0.2 AE running under AIX
> 4.3 with IHS 1.3.6 and the JDK 1.1.8. We are seeing some extensive
> garbage collection. Here is the heap size:
> 300 - 768 Mb
>
> On an average 45-50% of time spent on GC. For each GC, sometime it is
> taking 70sec, sometime even 120sec also. I am unable to understand how
> we can improve the GC.
>
> One reason, I can think of since we are doing cahing which is around
> 200MB and is available throughout the life of JVM.
>
> I have following questions:
> - Is there anyway to improve the GC?
> - Is there anyway to tell JVM to not look into the 200MB of cache
> data for GC.
>
> Another reason (may be), we are using
> Awaiting feedback.

> Thanks in advance.
