I installed Mathematica 12.1 on my Linux machine and the start-up time is extremely slow. I see the Spikey logo and messages like:

Initializing Kernel connections

It takes about 45 seconds to open a standard small notebook.

Running SystemInformation[], I get:

{
{" Version", "12.1.0 for Linux x86 (64-bit) (March 14, 2020)"},
{" Release ID", "12.1.0.0 (6765490, 2020031402)"},
{" Patch Level", "0"},
{" Activation Key", "XXXX"},
{" Machine ID", "XXXX"}
 }

{
{" Machine Type", "PC"},
{" Operating System", "Unix"},
{" Processor Type", "x86-64"}
 }

I also can see under Packages & Files that 88 packages and 221 files were loaded.

Is someone else experiencing the same problem?

I also have Mathematica 11.2 installed and there, the start-up time is about 2 seconds or less. All the messages from the Spikey logo are shown really fast. Looking at how many Packages & Files have been loaded, I see 30 packages and 183 files.

Could this be the problem? I have 16GB RAM and an Intel i7-8650U CPU.

    $\begingroup$ My Debian Buster VM takes approx 5 seconds for the kernels to fire up. Did you try renaming ~/.Mathematica out of the way? $\endgroup$ – ihojnicki Mar 25 at 21:38
