comment Can APC recognise duplicate source files?
Thanks, yeah that other question is also mine! The problem with symlinking, as you say, is that you need to use the same code. This can cause problems not only because of different versions, but also patches, and basically would require quite a major rethink to our current deployment process. That's exactly why I was hoping I could offload the whole problem onto APC. That way the development workflow still treats each site as entirely separate, but where there are identical files they don't each get cached separately.

comment Why does APC (or similar) cause performance problem for shared hosting?
There's no need to cache every file. Just like a processor has an instruction cache that doesn't hold entire programs, I would expect substantial gains to be possible by caching those files that are currently being used the most. See 3molo's answer for a possible reason why APC might not work in an appropriate way for this scenario though.

comment Why does APC (or similar) cause performance problem for shared hosting?
It doesn't actually say it will use LRU, it says it will expunge those whose TTL has passed. (And as the other answer noted, it's important to know what happens if there's no room and nothing has passed its TTL - maybe a complete purge.) Perhaps it's this lack of simple LRU system that makes it unappealing for shared hosting.

comment (Some) security perms in WinXP corrupted (shows GUID instead of username)
Sorry, have tried to clear that up a bit. There's been plenty of reboots since the new system was installed, so I don't know what sparked it off this morning.

comment (Some) security perms in WinXP corrupted (shows GUID instead of username)
Thanks. I think the reason the GUID isn't resolving is because it refers to an account on the previous server. (The question I guess then becomes why I could use my machine for the last month with no problems). I'll add the little bit of info that's in the logs to the main post. Network seems to be working fine: I've logged on and off multiple times, used files from the network (in fact I have redirected folders that seem to be working just fine). I also reset my machine more than once before posting this question. I don't fully understand the last bit of your answer :/

Thanks, yeah we have reseller accounts with Fasthosts and HostGator. I know they definitely don't do backup MX servers (unless of course you would like to purchase a dedicated server!). I've opened tickets to see if they do anything like DynDNS.com's MailHop Relay I describe above. DynDNS only charge USD 50 per year, so that's very affordable, but free would be better;)

Actually, I think it makes sense to use a service like DynDNS.com's MailHop relay. This just acts an intermediary, scans for spam/malware, forwards to your mail server if available, and queues if not.

Thanks for that, I guess I don't want to risk having just our local server as the MX server. Not sure whether to get a backup MX or just have Exchange pull from our main server. And thanks about the spam warning - that's exactly what the articles I've read have warned about, and they say it can be quite a bother for various reasons.
