Best practive for iRules-LX calls with a proc

Such an interesting question. It seems the last post does not answer the question.

I tried this code:

proc global_init_proc {handler} {
    ILX::call $handler -timeout 12000 HelloWorld
}

proc per_call_init_proc {} {
    set rpc_handle [ ILX::init HelloWorld HelloWorld ]
    ILX::call $rpc_handle -timeout 12000 HelloWorld
}


when RULE_INIT {
    set static::ilx_init_perf_report_loop 1000
}

when HTTP_REQUEST {
    set global_rpc_handle [ ILX::init HelloWorld HelloWorld ]
    set start [clock clicks]
    for {set i 0} {$i<$static::ilx_init_perf_report_loop } {incr i} {
        call global_init_proc $global_rpc_handle
    }
    set stop [clock clicks]
    set global_ilx_init_clicks [expr {$stop - $start}]

    set start [clock clicks]
    for {set i 0} {$i<$static::ilx_init_perf_report_loop } {incr i} {
        call per_call_init_proc
    }
    set stop [clock clicks]
    set per_proc_ilx_init_clicks [expr {$stop - $start}]


    HTTP::respond 200 content "
                
                    ILX Init Performance Report
                
                    ILX calls executed : $static::ilx_init_perf_report_loop times
                    when ILX init is done once : $global_ilx_init_clicks clicks
                    when ILX init is done in each call : $per_proc_ilx_init_clicks clicks
                
                
    " noserver
}

with ILX code:

var f5 = require('f5-nodejs');
var ilx = new f5.ILXServer();
 
ilx.addMethod('HelloWorld', function(req, res) {
    res.reply("Hellow World");
 });
 
ilx.listen();

This code execute 1000 times the proc running ILX for each scenario (ILX init in each proc or global)

here is the result:

$ curl http://192.168.2.11

            
                ILX Init Performance Report
            
                ILX calls executed : 1000 times
                when ILX init is done once : 283381 clicks
                when ILX init is done in each call : 289762 clicks
            
            

$ curl http://192.168.2.11

            
                ILX Init Performance Report
            
                ILX calls executed : 1000 times
                when ILX init is done once : 280417 clicks
                when ILX init is done in each call : 281854 clicks
            
            

$ curl http://192.168.2.11

            
                ILX Init Performance Report
            
                ILX calls executed : 1000 times
                when ILX init is done once : 281807 clicks
                when ILX init is done in each call : 285148 clicks
            
            

So we can say that the ILX init in each proc call uses a little more clicks than a global ILX Init.

but when running only 10 times the proc:

$ curl http://192.168.2.11

            
                ILX Init Performance Report
            
                ILX calls executed : 10 times
                when ILX init is done once : 3701 clicks
                when ILX init is done in each call : 2841 clicks
            
            

$ curl http://192.168.2.11

            
                ILX Init Performance Report
            
                ILX calls executed : 10 times
                when ILX init is done once : 10398 clicks
                when ILX init is done in each call : 10427 clicks
            
            

$ curl http://192.168.2.11

            
                ILX Init Performance Report
            
                ILX calls executed : 10 times
                when ILX init is done once : 3073 clicks
                when ILX init is done in each call : 2822 clicks
            
            

The the ILX init in each proc call is faster than global init.
