Processing: Processing opening slow in Windows

[sk0028]

I think it is a Java issue but I am not able to run processing as fast as it used to be initially. Opening processing takes about 10-15 minutes and running any program takes forever.

I've the same problem. I don't think it's java related as Processing2 opens and runs fine. I've tried 3 different machines (all Windows 7 ultimate) and I've been able to reproduce super slow loading times with java 8u111 (and 8u112) , with Processing 3.2.3.

If there's something else to try, let me know.　　

Edit: For me that was the proxy settings, as #3891

I get exactly the same issue, with Processing 3.2.3. I am behind a proxy at work and can't use Processing 3 in any reasonable amount of time (takes ~5 mins to load, haven't been able to get anything launching from it when it's loaded). I've got Processing 3 installed on multiple other machines that aren't behind a proxy and they work fine. I've also set proxy.http and proxy.https settings, but to no avail.

Just tried out Processing 2 and it works as expected.

I think this is because on startup Processing parses and opens all files inside the sketch folder path _including_ any compiled executables after the IDE first shows - the IDE remains unresponsive until all of these files have been read.
If your sketch path is on a network share and you run a packet sniffer, you can see the requests to open large compiled files. It also opens a collection of .jar and associated files but this may be required from certain folders. If you delete (or move) your compiled programs, you may find the load time reduces significantly.

mine opens very slow and cannot even run any result. :-(
