    I am aware of this.

    I have Litespeed, single physical server with 4 litespeed cores.
    What should i run?

    DSO or Fastcgi?
    APC or xCache
    Litespeed Built in Cache over that?
    VbOptimise?

    Does APC or XCache work fine with Litespeed? Where is the configuration details for that? im using litespeed 4.2.2

    DSO or Fastcgi?
    -- lsphp5 is fast cgi classs,

    APC or xCache
    -- either is ok. but ensure to run php in non-suExec mode, since APC or XCache not efficient or just waste in php suExec mode (shared hosting usually in suExec mode)

    Litespeed Built in Cache over that?
    VbOptimise?
    -- litespeed build in cache has no conflict with opcode cache(APC or xCache), it's a kind of page cache(link varnish), you can enable both.

    I think in eva's term,
    Litespeed web server and mod_php (DSO) non php suExec = litespeed + lsphp(run in non suExec mode)

    but lsphp itself belongs to fast-cgi class, not mod_php(DSO), mod_php(DSO) is only one of apache's php implementations.

    for best performance, we recommend
    litespeed + lsphp(run in suExec daemon mode).
    more detail, please refer

    What is the best op code cache in the daemon mode?
    xcache or apc?

    All looks fine.

    for best php performance, I'd suggest minimal "Configure Command" of php.
    and choose better performance one. for example,
    --with-mysql=/usr
    ==>--with-mysql=mysqlnd
    --with-mysqli=/usr/bin/mysql_config
    ==>--with-mysqli=mysqlnd

    you can start with --disable-all then add only needed more build options.
