Test code:

(defn fib* [a b n]
  (if (> n 0)
    (fib* b (+ a b) (- n 1))
    a))

(def fib (partial fib* 0 1))

(def l [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
           31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60])

(def t (time-ms))

(println (pmap (fn [x]
                 (fib x)) l))

(println "\n\n" "pmap" (- (time-ms) t) "ms")

(def t (time-ms))

(println (map (fn [x]
  (fib x)) l))

(println "\n\n" "map" (- (time-ms) t) "ms")

I got good results with this code.

_pmap_with_type () {
    local constructor="${1}"; shift
    local f="${1}"; shift
    local items="${ANON["${1}"]}"; shift

    # core count
    local cores=0
    while read -r line; do
        if [[ "$line" =~ "processor" ]]; then
            ((cores++))
        fi
    done < "/proc/cpuinfo"

    # create id for shared memory
    time_ms; local pmap_id="${ANON["${r}"]}"

    eval "${constructor}"; local new_seq="${r}"

    local index=0
    for v in ${items}; do        
        (
            eval ${f%%@*} "${v}" "${@}" 
            [[ "${__ERROR}" ]] && r= && return 1;

            str "${r}"
            echo -n "\"${ANON["${r}"]}\"" > "/dev/shm/_flk_pmap_${pmap_id}_${index}"
        ) &

        ((index++))
        
        # threads = cores + 1
        if [[ $(jobs -r -p | wc -l) -gt $cores ]]; then
            wait -n
        fi
    done

    # wait for inital threads
    wait
    
    index=0
    for i in ${items}; do
        READ_STR "$(</dev/shm/_flk_pmap_${pmap_id}_${index})"
        _conj! "${new_seq}" "${r}";
        rm "/dev/shm/_flk_pmap_${pmap_id}_${index}"
        ((index++))
    done
    r="${new_seq}"
}

So I will close the request.
