SLK slow to load large SCORM packages

I have an 80MB SCORM package exported from a commercial provider (Hodder Education - Dyanmic Learning) which has a large number of sections/chapters(?). When I try to run through SLK it takes 30 secs to load the cotent, then another 30 secs to browse from one section/chapter to another. The same package opens in moodle in a second. If I open the 50mb(ish) MS ProductivityProgrammes SCORM package it loads quickly in SLK; this package only has one chapter/section. Is there an issue with running large SCORM packages in SLK? Thanks

Runnking SLK 1.3.1 on WSS3 SP1.

Does it take the same length of time on subsequent runs? I know that the package is unpacked the first time it's accessed and then cached so it's going to be slower the first time - Moodle may well unpack it when it's loaded. Then again it shouldn't take 30 secs to browse between sections if that's the problem.

Hi Richard,

No it takes the same amount of time each time.

I have a similar elearning package of 250Mb and I have several versions of it.

The system always keeps cached 2-3 versions, but it doesn't seem to matter. Everytime a user accesses an assignment it starts loading (some times it may take up to 5'). 

This is because as I see, the system tries to uncompress the whole package again and again.

In moodle, the package remains cached in one single directory and it does not seem to recache everytime

I have the same issue. In some cases it takes longer then 30sec , is there a size limitations for scorm packages which should be used with SLK , I have been asked to put some BBC active stuff on VLE which is arround 650MB . I have tried with a 200MB package but its slow and students have reported error messages. when trying to use it.

Just wondered whether anyone had noticed improved performance in 1.4 in respect of this of this issue?

1.4 hasn't touched upon this area.
