When using the silentpay and orderresult services, there are performance limitations (the number of requests processed per unit of time):
- silentpay service processes up to 60 requests per second;
- orderresult service processes up to 100 requests per second.
If the specified request rate is exceeded, the maximum additional waiting time in the queue is 5 seconds (the first 8-16 requests will pass without additional waiting).
If the queue size is exceeded, a response with HTTP code 429 is issued:
<html> <head><title>429 Too Many Requests</title></head> <body> <center><h1>429 Too Many Requests</h1></center> <hr><center>nginx</center> </body></html>
These limits are system-wide and cannot be changed upon request.
