My library is more than 8 times your size and I have no stability issues.

That's good to know.  What are you using in terms of hardware?

I am using an Onyx Boox Tab 2 e-ink tablet.  It has been having glitches at times and I suspect it is due to the size of my library.  And also, as I said, I am no longer able to do backups directly unto the cloud - that worked until my library got to about 6GB.
I do not have the option of increasing memory on that tablet, and I plan to add lots more mp3s to my library, so I am looking into what might help at this point...
