Hello,
We have built an application based on WIAB 2.0.9.1. At the moment we are running into performance issues concerning memory usage.
What happens is that when an attachment is uploaded, in the form of an Attachments node, the node seems to be cached in a node cache, and by the time it is published to the live environment, several connections to the (MySQL) database are kept open in a connection pool. The cached node and the open connections each allocate a byte buffer roughly the size of the uploaded file. So uploading files eats away at the memory quite fast, resulting in an Out of Memory on the site.
Because WIAB is based on an old MMBase version (1.4?) we are looking into rewriting our application run on MMBase 1.7.1. This doesn't seem to be a trivial task.
Does anybody know about the issues I mentioned and if memory usage will improve if we port to MMBase 1.7.1?
Thanx in advance,
Michel
