Re: memory-mapped files in Squid

Hi

Reiserfs is optimised for many small files. It doesn't use block
allocations (if I remember correctly), so fragmentation is not really an
issue. The two problems are that it's:

1) complex. We don't really want this in Squid unless we know that it works
2) best implemented at the kernel level.
3) very processor intensive

I still have some testing to do as to speed etc. At some levels it's faster
than a netapp nfs server (over nfs). My tests indicated that it's
performance dropped dramatically with lots of files. I hope to prove
(sometime) that this drop is because of a lack of memory in my test machine
(and various other things that I have done wrong that Reiser told me to
try)
