KPRO Cache server is not effective

Question

Hi All,
When we checkout an assembly or a simple part from a remote KPRO the time is so long the second time than the first time.
If the cache serve should be effective, the second transfer should be really faster than the previous one and itu2019s not the case.
In the trace file below (dev_http) you can see the second transfer is not faster than the first one.
The normal transfer speed when we load a file from location is more than 3000 KB/s here we have a transfer around 330 KB/S for both transfers.
Please advise to rectify the performance.

Hi,
I have a similar problem but only with large files (i.e. over 200MB).  On the first request it doesn't cache and in the Application Log (SLG1) we see error mesage 04 102 "Time Limit exceeded" which looks like it is a SAPFTP error between Content and Cache server.
The user gets the file but it doesn't cache for next time.
Can you check your log to see if it's the same error?
Regards, Matt
