I can see that when the client download mtc.js javascrript for tracking it takes more than 450 ms to get the first byte.  
  
  
  
So, I assume that mtc.js is generated from php for each request… **is it so?**  
  
  
  
Can I make **mtc.js static** in some way?  
  
  
  
Thanks,  
  
Lorenzo

Could you tell me briefly why?

Thanks again

Actually, from what I see, this is indeed the case. There is no file “mtc.js” in the main mautic folder, but when I try to view it in a web browser: [https://www](https://www)._example_.co.il/mautic/mtc.js - it’s there.
