    For those on centos, downloading sqlite, and doing  ./configure --prefix=/usr/local then make/make install got me one step to getting the thing running.

    stuck on this now

    Code:
    /server.c:742: undefined reference to `evbuffer_get_length'
    /pushpool/server.c:744: undefined reference to `evbuffer_pullup'
    collect2: ld returned 1 exit status
    make[1]: *** [pushpoold] Error 1

    No problems compiling here... you may need to upgrade your libevent version and/or make sure you have the libevent-devel package installed.

    Yes.  0.4 does not introduce any breaking changes for pushpool.

    Trying to fire up a pool on Ubuntu Server 10.04.3. Using libmysqld-dev. configure and make run fine, but I can't start pushpoold. There are no outputs.

    How to get it running?

    You need to install postgresql, mysql and/or sqlite development libraries.

    I have created a pool http://alvarez.sfek.kz based on pushpool. Everything works fine but for some reason a lot of prevhash-stale and duplicate stale errors. How can I fix these errors to have been less? The rate of the pool until 2 may be necessary to add memory or remove support for memcached?

    Is there a way to configure the difficulty of the work units issued to miners?

    My understanding (please correct me if wrong) that pretty much all mining pools (exception of p2pool) use a difficulty of 1 for work units.  I'm concerned with the ASICs coming down the line that will be too many work units and create trouble for mining pools and miners.

    With my two BFL singles I see a work unit every few seconds.  With an ASIC 40GH/s single I would expect to see many per second which seems to be unnecessary network chatter and unnecessary DB work for the pool.

    Absolutely, the diff can be changed.  Just a couple constants, and an additional check.

    What are the performance limits of PushPool?
    In particular: How many concurrent workers can be connected concurrently? And how much bandwidth/disk space/ram is needed per worker?

    It will not scale past a few hundred GH/s. 
    If you're searching these lines for a point, you've probably missed it.  There was never anything there in the first place.

    Thanks.
    I am not interested in hashing power (yet), but more in the number of workers that it can handle and how it can scale against with their increase. What would the bottleneck be? Software bounds, ram, etc... ?

    Software bounds and back end share storage.

    I see. So does it require increasingly more space as workers are added to the pool or is that mostly by the size of the blockchain computed so far?

    Neither, it just simply can't scale and gets behind and eventually fails completely.

    Do you have any more technical details?

    Does this apply with the 0.7 bitcoind upstream, with vastly revamped RPC?

    I've not tried on .7.  I had to move on to other software quite awhile ago when I could no loner get Pushpool to scale past about 400 GH/s, and even that was with multiple servers running. 

    It's entirely possible the new .7 release would solve some of the problems, but the lack of threading for database access is a real problem for large scale operations.
