Opening Items in the list causes delay

[srimans]

• Expanding items in the item list causes lagging.It takes some time to expand in some cases.The number of items were more than some close or more than 1000s (Eg: 6377,13092,857 etc..) .
• Few times white screen is seen for a while on repeated clicking.
  Once it opens up,the behaviour is fine

Hi @srimans ,

Thanks for your finding. This is a known performance issue that tend to be ignored so far.
