However, copying a file over the network that usually runs at about 90 MB/s slows down to 25 MB/s. CPU load of the passthru program is between 20 and 25%.\r\n\r\nDoes WinDivert really slow down network traffic that much? Can this be improved? Other solutions, like WinpkFilter, have a much smaller impact (e.g. just 5% CPU load, just 10% drop in transfer rate).\r\n\r\nThanks!"},"comment":{"url":"https://api.github.com/repos/basil00/Divert/issues/comments/248848671","html_url":"https://github.com/basil00/Divert/issues/52#issuecomment-248848671","issue_url":"https://api.github.com/repos/basil00/Divert/issues/52","id":248848671,"user":{"login":"Areithus","id":22146095,"avatar_url":"https://avatars.githubusercontent.com/u/22146095?v=3","gravatar_id":"","url":"https://api.github.com/users/Areithus","html_url":"https://github.com/Areithus","followers_url":"https://api.github.com/users/Areithus/followers","following_url":"https://api.github.com/users/Areithus/following{/other_user}","gists_url":"https://api.github.com/users/Areithus/gists{/gist_id}","starred_url":"https://api.github.com/users/Areithus/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Areithus/subscriptions","organizations_url":"https://api.github.com/users/Areithus/orgs","repos_url":"https://api.github.com/users/Areithus/repos","events_url":"https://api.github.com/users/Areithus/events{/privacy}","received_events_url":"https://api.github.com/users/Areithus/received_events","type":"User","site_admin":false},"created_at":"2016-09-22T09:05:23Z","updated_at":"2016-09-22T09:05:23Z","body":"Did you ever find anything to improve the performance? I'm currently experiencing a similar performance drop and high CPU usage. The application spends most of its time in the WinDivertSendEx method. I already increased both available parameters (WINDIVERT_PARAM_QUEUE_LEN and WINDIVERT_PARAM_QUEUE_TIME) but that does not make a lot of difference I'm afraid."}}
