[OpenAFS] 1.3.x memcache performance

[Andrej Filipcic]

Hi,

I have checked diskcache/memcache performance over an ADSL link.
The link has 4M download and 512k upload bandwidth. Although there are still 
problems with disk cache, the copy from afs to local disk is good enough.
With disk cache the speed is ~400 kbyte/s (tcp speed is 500 kbyte/s).
Memcahe speed is much lower, between 120 and 160 kbyte/s, depending on the 
fileserver. Is there any reason (bug) for such a big difference?

On gigabit network, the copy speed with memcache is never larger than 20 
mbyte/s, with disk cache it can go up to 70 mbyte/s.

Servers are 1.2.13, the client is 1.3.77.

Cheers,
Andrej
