We are using Delphi XE4 Pro Version 18.0.4854.59655.
In our application we have used Indy10 FTP Client component active mode for file transfer purpose. We want to transfer file of size 39KB. We have observed that while file transfer, after TCP packets has been received by delphi app, TCP acknowledgement is sent after a delay of around 200msec. As there are multiple packets to be sent, because of this delay, total file transfer time is very long.
For ready reference, I have attached Wireshark capture file Testwith1000.pcapng.
Is there any method to reduce TCP ack delay ?
We are using Delphi XE4 Pro Version 18.0.4854.59655 .
In our application we have used Indy10 FTP Client component for file transfer. File size is around 39KB.
We have seen that after receipt of TCP data packet, PC is sending TCP ack delayed by around 200msec. Hence next packet from FTP server is getting delayed. Hence total file transfertime is very long.
Is there any method top reduce this TCP ack time ? For your ready ref, please see file attached for timings.
We are using Delphi XE4 professional for our software application. We want data base development using MS SQL server express. On using TSQLConnection, we are getting MSSQL unknown drive name error and asking for dbxmss.dll file. (Win 32 bits)
We have checked for this dll but it is not found on our computer.
