Which is better to use - EHCache, OSCache or Swarmcache

[2devnull]

I have some relatively large XML documents that I would like to cache for a period of time. I already cache the query from the DB using OSCache with Ibatis SQL Maps. I would like to know you opinion of caching the XML document that is then create from this data. Would you suggest using EHCache, OSCache or SwarmCache? Why?

If you have done this analysis before, please share any performace results you may have. Thank you.

I think JBoss Cache is better . JBoss cache is a fully transactional, cluster-safe caching system.

Take a look at Table 14.1. Cache Providers, it summarize some of the differences between these cache providers.

Funny thing, I was reading 'Hibernate in Action' this weekend and saw the comparison in the book. Thanks though.

I decided to go with Ehcache and re-used Ben's code and bean set up for what was done in Acegi. I wanted to use OSCache but the documentation is very weak.

Great choice

Spring Framework 1.1.1 allows for configuring EHCache using IOC. Take a look at package org.springframework.cache.ehcache (in cvs) for more details.

If I were starting a new project, I'd use Spring's new org.springframework.cache.ehcache package. Acegi Security will be depreciating its implementations in favour for this package once it's in a Spring core release.

Thanks Ben. I took irboubo advise and got the package you metioned from CVS. I also updated my AGEGI provider to use it. Work fine so far.

A newbie question. Is com.method.util.EhCacheBasedUserCache a class of your own? How does it look like?

[asmuts]

I'm working a basic comparison of EHCache and JCS. The JCS disk store is much more sophisticated and the JCS LRU Memory cache appears to be twice as fast as EHCache.

I think JBoss Cache is better

+1

If you're building a system that can run on one box, by all means use the other caches, but if you have 2 or more servers then your only practical choice is JBoss TreeCache.
