Slow File Copy in ICA Sessions When Latency Between Client and VDA is High
Article ID: CTX222363
Updated On:
Description
Time taken to copy files from client to local hard drive on VDA is slow compared to RDP.
Assume latency from client to VDA is 50ms. Copying a zip file from the VDA to a mapped client drive takes 13m40s with ICA .
In RDP it takes 5m 05s. If there is no latency then file copy times between ICA and RDP are similar.
Resolution
As latency is a factor the TCP buffers must be optimized as per CTX125027- How to Optimize HDX Bandwidth Over High Latency Connections. In this instance after Setting OutBufCountClient2 and OutBufCountHost2 o= 195 on the client file copy performance in ICA is comparable to RDP. However the values must be configured on a case by case basis depending on the network.
Problem Cause
Issue is seen when there is high latency between the client and the VDA.
