Alternative to pm2

Hello, I would like to come to your help again. Since I usually get very accurate answers that help me to advance a lot and learn more about servers and the use of cyberpanel.

My forte is programming but currently in my job I have to deploy and work as devOps

I am deploying some angular ssr on my server with cyberpanel. For this I use pm2 and using vhost config

this way:

docRoot                   /home/
vhDomain                  $VH_NAME
vhAliases                 www.$VH_NAME
enableGzip                1
enableIpGeo               1

index  {
  useServer               0
  indexFiles              index.php, index.html

errorlog $VH_ROOT/logs/ {
  useServer               0
  logLevel                WARN
  rollingSize             10M

accesslog $VH_ROOT/logs/ {
  useServer               0
  logFormat               "%h %l %u %t "%r" %>s %b "%{Referer}i" "%{User-Agent}i""
  logHeaders              5
  rollingSize             10M
  keepDays                10  
  compressArchive         1

errorpage 403 {
  url                     403.html

errorpage 404 {
  url                     404.html

errorpage 500 {
  url                     500.html

scripthandler  {
  add                     proxy:miweb123 html

extprocessor miweb123 {
  type                    proxy
  maxConns               2000
  initTimeout                20
  retryTimeout                0
  respBuffer                0

module cache {
 storagePath $VH_ROOT/lscache

rewrite  {
  RewriteCond %{HTTP:UPGRADE} ^WebSocket$ [NC]
  RewriteCond %{HTTP:CONNECTION} Upgrade$ [NC]
  RewriteRule /(.*) ws://$1 [P]
    enable                  1
    autoLoadHtaccess        1
context /.well-known/acme-challenge {
  location /home/
context / {
  type proxy
  handler miweb123
  addDefaultCharset off

vhssl  {
  keyFile                 /etc/letsencrypt/live/
  certFile                /etc/letsencrypt/live/
  certChain               1
  sslProtocol             24
  enableECDHE             1
  renegProtection         1
  sslSessionCache         1
  enableSpdy              15
  enableStapling           1
  ocspRespMaxAge           86400

But this puts a huge load on my server on its ram and cpu.

Is there an alternative to avoid this problem?
Maybe an alternative to pm2 using litespeed’s internal proxy?

I really appreciate any help you can give me.
