| 3 | | (1)2000 requests per millisecond, which also mutexes the count（ngx_shmtx_lock）, so that if only 1,000 requests are allowed per second, the next 1,000 will be rejected。Is that wrong? |
| | 3 | (1)2000 requests per millisecond, which also mutexes the count（ngx_shmtx_lock）, so that if only 1,000 requests are allowed per second, the next 1,000 will be rejected。And the update request count is as follows： |
| | 4 | If (now-last)/1000*limit_count is greater than req_count, then req_count=0; otherwise, req_count-(now-last)/1000*limit_count 。 Is that wrong? |
