mickeyd453 Posted December 3, 2020 Share Posted December 3, 2020 Hi Now i have a stable legacy system running OC one thing that is apparent to me is that compared to _exactly_ the same system booted with clover the response of the system is pretty laggy and noticeably slower in everyday tasks. What would be the best way to go about figuring out what is causing this lag in the system and then resolving it as at the moment i cant migrate from Clover to OC as day to day its quite unusable. Kexts are identical between Clover and OC. As a very basic test i timed a diskutil command as i noticed that when running that it was visibly slower to complete. Data indicated a significant difference in response time. OC imac:~ mick$ time diskutil list real 0m0.536s user 0m0.183s sys 0m0.116s imac:~ mick$ time diskutil list real 0m0.518s user 0m0.182s sys 0m0.115s imac:~ mick$ time diskutil list real 0m0.516s user 0m0.182s sys 0m0.119s Clover imac:~ mick$ time diskutil list real 0m0.151s user 0m0.038s sys 0m0.041s imac:~ mick$ time diskutil list real 0m0.118s user 0m0.038s sys 0m0.030s imac:~ mick$ time diskutil list real 0m0.126s user 0m0.038s sys 0m0.034s any clues as to where to start with this one? cheers Link to comment Share on other sites More sharing options...

This board does in fact run BS very well under clover so i guess i'll leave it be for the time being as its working well. Link to comment Share on other sites More sharing options...
