Hi I've found that some of my charts take much longer to load now. So I've carried out some tests with different versions and found the following: The same chartbook shows very different loading times for the same VbP study and chart: 950ms in version 1727 32 bits vs 39377ms in version 1834 64 bits Same lazy behavior is found in other recent versions. The difference is even greater when using Range 2 bars. Find attached the chartbook used and an annotated image Thanks |

We posted a response and did not notice any performance issue, but we realized we were testing on 1727. The apparent reason for the issue is performance improvements which apparently are having a detrimental impact with the particular configuration you are using which is a large number of volume profiles that consist of a small number of prices. There is going to be more memory use in this case. Otherwise, there is definitely a performance improvement in newer versions. We will work on some solutions this weekend.

Okay we now have the calculation time reduced back down to what it was before. We understand the basis of the problem. There were previous performance improvements, but when there are a large number of volume profiles in the chart like you have, which is actually over about 30,000, there is a negative performance impact but we have that now solved.
