Is it normal behaviour when EPOserver uses a lot of memory (typically 200-500 MB)?
Yes. This is caused by the fact that EPO is developed in .NET. There is a lot of information on the subject “memory usage by .NET” on the Internet – you can find out about this more by “google”-ing for “.net memory usage”. In short it comes down to: “for optimal performance .NET uses relatively much memory, but if another application asks for memory(resources) .NET will back down and releases memoryresources”. Our summary: “Memory is there to be used in stead of not being used”.
