Memory usage of SageTVService

[rswoods]

Quick question: Is is normal for the SageTVService to use more than 150MB of ram? On a fresh restart it uses about 58MB, but soon thereafter it goes to over 150MB.

Just wondering if this is normal..

Thanks

Edit to say apparently it is normal...

never mind...

I think it grows to the Java VM heap size limit, configurable

I've asked this question before without an answer, so I'll use this opportunity to ask again:

If your SAGE box is dedicated (e.g. you're not using it to browse or do taxes or play games) and you've topped out the RAM supportable by 32bit Windows, what are the best JavaVM heap sizes for increased stability? If the answer is, 'it depends', then what does it depend on?

My opinion is the best heap size is whatever your system needs. If you are regularly maxing it out, then increase it. If you aren't using all your ram and Sage needs more then increase the size. Most of us have 512 (shows at 533) available. That seems to be sufficient for my setup. I don't think any of us know the exact variables that say with "X clients you need X amount of java heap"....I've even considered increasing my java heap size since I still have about a gig of ram available in my dedicated Sage Server even though I probably don't need it.

This does sound increasingly like a reactive 'give it what it needs', but there doesn't seem to be an instrumentation to measure that other than 'is it hurting now?'

The reactive engineering is what I'm trying to avoid. Does anyone who does Java programming or support know if there is a sweet spot in heap assignment for the JavaVM?

Task manager usually shows the SageTV service running at about 250MB on mine. I have not made any modifications to Java or anything else.

I know with 2GB (previously 1GB) now in the system it does tend to use the extra RAM. The % usage is about the same at peak (75~79%) but naturally much lower under "normal" circumstances.
