Collaboration portal Performance

Hello All,

We are using TMS9.1 at SP07 version with collaboration portal (NW7.4 version).

We have recently implemented

2176358 - Collaboration Portal: Time-dependent cache reset (back end)

2176359 - Collaboration Portal: Time-dependent cache reset (front end)

2180889 - Collaboration Portal: HTTP request failed when accepting invoice or creating dispute

But we are still experiencing the performance issue in production. When the carriers login from the external link , portal takes lot of time to load the screen. When we installed the same in quality we didn't experience such issues.

Did anyone experience such issue?

Any advise will be really appreciated.

Regards

Anand
