I have a client who is using the trial version (on a new HP ML350 G6 with 12GB RAM allocated to the VM) for their office of six. They like the product, except it will get very slow for several minutes a few times per day. When store.exe has a reasonable amount of memory allocated (usually for a while after a restart) the problem does not happen. Right now, it has almost 5GB allocated.
I have read several articles online regarding adjustment of the msExchESEParamCacheSizeMax. There are conflicting numbers out there about the actual size of the cache blocks, so I am not actually sure I am limiting yet having it set to 50,000. I have reduced this number by about half each time, having done this maybe four times now (I think I started at 500,000 when I errantly thought the blocks were 4KB each - I am still not sure what they are [have seen both 8KB and 32KB mentioned in support docs])
The server does have Trend Micro Worry-Free Business Standard on it, using their latest version whose patch level (1435) is supposed to be SBS 2011 compatible. I can pretty well guess they might be part of the issue, but I still should be able to limit the cache independently.
Please advise. Thanks, Tom.
