I’m currently using the vscode Julia extension when working remotely on Frontera, a supercomputer (CentOS 7). Recently the extension becomes weirdly slow; when I try to execute a code block, it takes about 1 minute to start the REPL; typing in the REPL can be extremely laggy, and it take 3-15 seconds for a command as simple as 1+1 to finish.
These problems also occur sometimes when Julia is started in bash; playing with plain Julia from bash for a while seems to to able to ease the problem with Julia REPL, probably because of warming-up effects?
The problem occurs with Julia 1.9.0 and 1.6.1.
Any suggestion about what’s going on here?
