I downloaded the Apache module mod_bw to see if I could simulate some "slow" connections. To compile the package you need to run the following command as root:

# apxs -i -a -c mod_bw.c

That will install the module correctly, but when you add the configuration option to your vhost configs you might get an error "undefined symbol: apr_atomic_cas". When that happens, open the file mod_bw.c and change the following:

Before:

/* Compatibility for ARP < 1 */
#if (APR_MAJOR_VERSION < 1)
    #define apr_atomic_inc32 apr_atomic_inc
    #define apr_atomic_dec32 apr_atomic_dec
    #define apr_atomic_add32 apr_atomic_add
    #define apr_atomic_cas32 apr_atomic_cas
    #define apr_atomic_set32 apr_atomic_set
#endif

AFTER

/* Compatibility for ARP < 1 */
/*
#if (APR_MAJOR_VERSION < 1)
   #define apr_atomic_inc32 apr_atomic_inc
   #define apr_atomic_dec32 apr_atomic_dec
   #define apr_atomic_add32 apr_atomic_add
   #define apr_atomic_cas32 apr_atomic_cas
   #define apr_atomic_set32 apr_atomic_set
#endif
