Memory upgrade
I ran vmstat today and I noticed that there was a bit of swapping going on (memory swapping that is, not rumpy-pumpy). I think the reason is that I increased the Apache max clients, but this was required because the server had ground to a halt. Also, I am about to deploy memcached with an initial 64MB so it looks like there’s a need for a bit more memory.
I’ve decided to upgrade from 1 GB to 2 GB which should keep me going for a bit. It’s a $39.99 setup and then an extra $39.99 per month from ServePath. This seems bit steep given that an extra 1 GB from Dell is a one-off $70!
I also considered upgrading the slightly elderly processor but I think that extra memory will have much more impact.
