I'm finding this on my ARMini. Is this common? Presumably using !Cache on a RAM disc would be a waste of time as stuff would not be saved when the computer was turned off.

If during one use of the computer (ie until you next turn it off) you visit multiple pages from any site the cache will still satisfy some of the fetches they require. You could run an Obey file just before you shut down to copy stuff from RAM disk to real disk, and reverse that process soon after booting, though I think if you did you'd need to prune the cache somehow. -- Jeremy C B Nicoll - my opinions are my own.

Is this common? I get it on my SAM440 very frequently. I'd be very surprised if the write bandwidth was that low as it's a fast SATA drive. Curiously I've never seen the message on my old EEE, which has the slowest SSD write times known to man (it's slower than any HDD I've encountered). I suspect the OS has a lot to do with it, especially when writing lots of small files there's likely to be significant overhead. Chris

It's maintained by Fred Graute, but his Iconbar site doesn't seem to be available at present. Memphis is a RAM disc that saves itself at shutdown and loads itself at startup if you configure it to do this. Best wishes, Peter. -- Peter Young (zfc Re) and family Prestbury, Cheltenham, Glos.

The Cache can grow - by default it is set to 1 GB. It would soon overflow the available RAM if you tried to save it over sessions. -- Chris Johnson
