Subject: [PATCH] curl_easy_perform: gradually increase the delay time |
|
|
|
Instead of going 50,100,150 etc millisecond delay time when nothing has |
|
been found to do or wait for, we now start lower and double each loop as |
|
in 4,8,16,32 etc. |
|
|
|
This lowers the minimum wait without sacrifizing the longer wait too |
|
much with unnecessary CPU cycles burnt. |
|
