| Darn....
Yes, in fact FRED was down this morning.
The database server died overnight, probably during the nightly maintenance & backup routines. I've restarted it and FRED should be all better now.
Thanks to the several people who emailed me to let me know.
Please accept my apologies for the inconvenience during this lapse in service.

-p | Just keep FRED up over 324 days, 10 hours and 30 minutes or so (time not precise to 6 digits) | |

| FRED needs a bigger house
Well, this weekend's outage has prodded me to do what I've been needing to do for a little while anyway: get FRED a bigger machine to live in. He seems to outgrow his house about once a year. This time it took more like a year and a half, so that's cool, but this time the step up will not be as big a step as before, so I'm not sure how long this next machine will take the load.
Only time will tell......

| sweet.
Are you more RAM, CPU or disk bound? I'd imagine RAM or disk, given they took the biggest jump. As I understand it, CPU bound tasks do well with HT enabled, but other ones do better with it disabled. (Or maybe I have it backwards.) I'm pretty sure I'm right the first way, since if you're memory bound then cache thrashing from the Hyperthreading will hurt more. | |

The main thing is the RAM. FRED's been swapping too much, I think mostly because of the DB. When the current server was new, the swap was almost nil, now it's anywhere from 200M to 1G (during backups).
So the extra RAM will be nice.
The CPU also gets up into the 60% range at times (usually during backups), but most of that is IOwait, not user process. There are other times, however, when the load really spikes. A fair amount of CPU gets spent on spam filtering and virus scanning. Almost as much as the actual web & db service sometimes.
The drive space is just a nice extra. The backup (secondary) drive is pretty full right now, so the extra room is nice but it's not the main driver for moving.
Of course, I'm not really the biggest hardware expert, so....

| My understanding is that databases are supposed to be excluded from anti-virus scans. I presume you've done that? | |

-p | I use that joke in presentations on reliability. "You want 5 9's? Hah, that's nothing, I'll give you 10 8's!". Works like a charm...
