Hello
It's time to realize that we haven't enough servers in our cluster. One goes down, and we have problems.... And wikpedia is slow !
It would be really a good idea to get 2-3 more servers to be used as apache or squid.
Another thing, zwinger our nfs server needs fast access in reading, cause each time a user requests a page, it hits at least one file on zwinger... A nfs server with a raid1 ide drive, would be fine I think and it would improve reliability(big disks of course, we begin to be short of space on zwinger too. 4G left with only 2 backups). The actual squid server could be used as an apache server then.
And of course DB SERVER !!!! We have compressed old table on Suda to keep saving some space, but we're really short in space. And we can't migrate other wikipedias as de, nl, ... to UTF-8 before getting more space and speed. There is only 3G left on Suda, and we need space for logs. So we copy often logs to another server... If space is full, we'll have to use Curly as DB server, with only one ide drive, back in time in december when wikipedia was so slow (yeah, I know it's slow now, but it was worse in december)
Wikimedia must get new servers to improve speed. At least for those who has given money !
