It's around 7GB at my place - probably heavily depends on SleepycatDB
version. With log autoremove option I have these sizes for each of
directories:

 6.8G   .
 5.7G   KDB
 103M   PTree

During the years I have seen SKS use very little CPU, but memory is
another issue. SKS itself is very modest with usage [except when doing
pbuild/build/clean], but through DB_CONFIG you can increase memory usage
[around 130MB RSS at my place] and get some additional performance. My
configuration is as follows:

$ cat DB_CONFIG
set_cachesize 0 100000000 10
set_flags DB_LOG_AUTOREMOVE
set_lg_max 10485760
set_lg_bsize 2097152
set_lg_regionmax 262144

I believe that should suffice. Generally more peers will cause more
traffic - yet our SKS server never showed on network reports as seriuous
bandwidth eater.

You e-mail here and get people to reply to you with their SKS peers. Each
of you should put each other in their membership file and that's it.
