Git status takes too long- How to improve the performance of git

0 votes
137 views

We are using git-1.8.2 version for version control. It is an centralized server and git status takes too long

How to improve the performance of git status

Git repo details:
Size of the .git folder is 8.9MB
Number of commits approx 53838 (git rev-list HEAD --count)
Number of branches - 330
Number of files - 63883
Working tree clone size is 4.3GB

time git status shows
real 0m23.673s
user 0m9.432s
sys 0m3.793s

then after 5 mins
real 0m4.864s
user 0m1.417s
sys 0m4.710s

And I have experimented the following ways
- - Setting core.ignorestat to true
- - Git gc &git clean
- - Shallow clone €“ Reducing number of commits
- - Clone only one branch
- Git repacking - git repack -ad && git prune
- - Cold/warm cache

Could you please let me know, what are the ways to improve the git performance ?

Can you try sparse checkout, which will bring only the directories of interest(only those directories on which you make code change) to your system, so while doing git status it will try to search locally only those directories you checked out.

Share your experience after that.

Below table contains billion of rows,

CREATE TABLE `Sample1` (
  `c1` bigint(20) NOT NULL AUTO_INCREMENT,
  `c2` varchar(45) NOT NULL,
  `c3` tinyint(4) DEFAULT NULL,
  `c4` tinyint(4) DEFAULT NULL,
  `time` bigint(20) DEFAULT NULL,
  PRIMARY KEY (`c1`),
  KEY `varchar_time_idx` (`c2`,`Time`),
  KEY `varchar_c3_time_idx` (`c2`,`c3`,`Time`),
  KEY `varchar_c4_time_idx` (`c2`,`c4`,`Time`),
  KEY `varchar_c3_c4_time_idx` (`c2`,'c3', `c4`,`Time`),
) ENGINE=InnoDB AUTO_INCREMENT=10093495 DEFAULT CHARSET=utf8

Four multi column index created because having below conditions in where

1) c2 and time
2) c2 and c3 and time
3) c2 and c4 and time
4) c2 and c3 and c4 and time

Cardinality wise c2, c3 and c4 are very low. (ex: Out of one million c2, c3 and c4 have 50 unique column in each)

Column time contains mostly unique fields.

Select, insert and update happened frequently.

Tables has 5 indexing fields(4 multi column). Due to this, 1) Insert and update on index fields become costlier. 2) As the table keep on growing (Nearly one billion rows), Index size also increase more rapidly.

Kindly suggest good approach in mysql to solve this use case.

I've a table with 10 Million records in MySQL with INNODB engine. Using this table I am doing some calculations in STORED PROCEDURE and getting the results.

In Stored Procedure I used the base table and trying to process all the records in the table. But it's taking more than 15 Minutes to execute the procedure. When executing the Procedure in the process list I am getting 3 states like 'Sending data', 'Sorting Result' and 'Sending data' again.

Then I created one view by using the base table and updated the procedure by replacing that view in the place of a base table, it took only 4 minutes to execute the procedure with a view. When executing the Procedure in the process list I am getting 2 states like 'Sorting Result' and 'Sending data'. The first state of 'Sending data' is not happened with view, It's directly started with 'Sorting Result' state.

When I'm referring some MySQL sites and other blogs, I have seen that VIEWS will never improve the performance. But here I see some improvements with a view.

I would like to know how VIEW is improving the performance.
