Re: [twsocket] SSL post extremely slow

Either way, if the problem is the async nature of ICS, shouldn't an alternate method be provided? Try with the TransmitFile function https://msdn.microsoft.com/en-us/library/windows/desktop/ms740565(v=vs.85).aspx You may create a descendant of the THttpCli, override the SocketDataSent

GET seems fine though. You mentioned changing the buffer size, where would you do that? I tried changing 8k to 64k in OverbyteIcsHttpProt.pas here, but it made no difference: ~4617 procedure THttpCli.SocketDataSent(Sender : TObject; ErrCode : Word); var Len : Integer; begin if not

Note that the original subject is a bit misleading, the issue is not about ssl POST, but POST in general, whether on http or https. On Thu, May 12, 2016 at 12:13 PM, Angus Robertson - Magenta Systems Ltd < an...@magsys.co.uk> wrote: > > I still have some Windows 7 VMs, so will do more testing

Re: [twsocket] SSL post extremely slow

Alright I'm back with some interesting results that confirm my suspicions (actually meant 300/30 Mbit btw) * All VM tests (xp/w7/w10/ubuntu) showed similar results around 0.9..1MB/s upload, except when using a UK VPN: ICS was again slow. * Win XP on a netbook on wifi (Asus eee901): ICS: 65.8s.

Re: [twsocket] SSL post extremely slow

Yeah, I'm on 100/30 Mbit fiber, Windows 7 x64 and the latest V8 SVN with Delphi Seattle. Some days ago I tried an old V5 with Delphi7 to rule out this problem having been recently introduced, but I observed the same results. Since you mentioned Windows 10, I thought of making a few extra tests

Re: [twsocket] SSL post extremely slow

You never mentioned you were testing the synchronous methods of the component, that is not a fair test of ICS performance, you should be using proper events and the async component methods. I'm observing the same issue with async calls though, did the same test from above but this time with
